    • The present invention relates to a process for producing a trifluoromethylbenzylamine represented by the general formula (1), 1 where R1 represents hydrogen atom, a halogen atom selected from the group consisting of fluorine, chlorine, bromine and iodine, or trifluoromethyl group. This process includes the step of reducing an oxime by hydrogen in an organic solvent in the presence of a catalyst and ammonia. The oxime is represented by the general formula (2), 2 where R1 is defined as above, and R2 represents hydrogen atom, an alkyl group or an aralkyl group. With this process, the trifluoromethylbenzylamine can be produced with high yield.
    • 本发明涉及由通式(1)表示的三氟甲基苄胺的制备方法,其中R1表示氢原子,选自氟,氯,溴和碘的卤素原子或三氟甲基。 该方法包括在催化剂和氨的存在下,通过有机溶剂中的氢还原肟的步骤。 肟由通式(2)表示,其中R 1如上定义,R 2表示氢原子,烷基或芳烷基。 通过该方法,可以高产率制备三氟甲基苄胺。
