第1工程
式Iで示される化合物に、式IIで示される化合物を反応させ、式IIIで示される化合物を製造する工程である。
本工程は、アミンとカルボン酸からアミドを製造するために使用される一般的な合成法を使用することができる。例えば、酸クロリドを式Iで示される化合物に反応させ、混合酸無水物に変換し、式IIで示される化合物を反応させることにより、式IIIで示される化合物を製造することができる。混合酸無水物の製造は、塩基の存在下で行うことが好ましく、例えば、塩基として、トリエチルアミン、ピリジン、N,N-ジメチルアミノピリジン、DBU(1,8-ジアザビシクロ[5,4,0]ウンデセ-7-エン)等を用いることができる。
溶媒としては、トルエン、ジメチルホルムアミド、テトラヒドロフラン、酢酸エチル、アセトニトリル等を用いることができる。反応は、0〜100℃、例えば、室温で行うことができる。
First Step In this step, a compound represented by formula II is reacted with a compound represented by formula II to produce a compound represented by formula III.
In this step, a general synthetic method used for producing an amide from an amine and a carboxylic acid can be used. For example, a compound of formula III can be prepared by reacting an acid chloride with a compound of formula I, converting it to a mixed acid anhydride, and reacting a compound of formula II. The mixed acid anhydride is preferably produced in the presence of a base. For example, as a base, triethylamine, pyridine, N, N-dimethylaminopyridine, DBU (1,8-diazabicyclo [5,4,0] undec -7-ene) and the like can be used.
As the solvent, toluene, dimethylformamide, tetrahydrofuran, ethyl acetate, acetonitrile or the like can be used. The reaction can be performed at 0 to 100 ° C., for example, at room temperature.
第2工程

還元剤としては、アミドの還元に使用できる還元剤であればよく、例えば、Red−Al(ナトリウム ビス(2-メトキシエトキシ)アルミニウムヒドリド)、リチウムアルミニウムヒドリド、ボラン等を用いることができる。特に、Red−Alが好ましい。還元剤の量は、式IIIで示される化合物に対し、1〜10当量使用することができる。例えば、Red−Alの場合、1〜6当量、例えば、4当量使用することができる。溶媒としては、トルエン、ベンゼン、テトラヒドロフラン、ジオキサン等を用いることができる。反応は、0〜100℃、例えば、室温で行うことができる。
Second Step In this step, the compound represented by the formula III is reduced to obtain the compound represented by the formula IV.
The reducing agent may be any reducing agent that can be used for amide reduction. For example, Red-Al (sodium bis (2-methoxyethoxy) aluminum hydride), lithium aluminum hydride, borane, and the like can be used. In particular, Red-Al is preferable. The amount of the reducing agent can be used in an amount of 1 to 10 equivalents relative to the compound represented by Formula III. For example, in the case of Red-Al, 1 to 6 equivalents, for example, 4 equivalents can be used. As the solvent, toluene, benzene, tetrahydrofuran, dioxane or the like can be used. The reaction can be performed at 0 to 100 ° C., for example, at room temperature.

特に、以下の化合物の塩又は水和物が好ましい。これらの塩は結晶化し、融点も高いので、工業的に使用しやすく、精製も容易であり、抗菌剤を合成する上で、非常に有用である。
Since the compound represented by the above formula is easily dissolved in hexane or the like, it is difficult to isolate it in a high yield. Moreover, it does not crystallize in the methanol / water system. As a result of studying various salts, the present inventor considered isolation as a salt, and as a result, hydrochloride, sulfate, phosphate, p-toluenesulfonate, camphor-10-sulfonic acid (CSA) salt ( For example, (1S)-(+)-camphor-10-sulfonate) was found to be preferred as the salt of this compound.
In particular, salts or hydrates of the following compounds are preferred. Since these salts crystallize and have a high melting point, they are easy to use industrially and easily purified, and are very useful for synthesizing antibacterial agents.
