The present invention relates to a process for producing a trifluoromethylbenzylamine represented by the general formula (1),
1
where R
1
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 R
1
is defined as above, and R
2
represents hydrogen atom, an alkyl group or an aralkyl group. With this process, the trifluoromethylbenzylamine can be produced with high yield.
本发明涉及一种制备三氟甲基苯基胺的方法,其通式表示为(1),其中R1代表氢原子、从氟、氯、溴和碘中选择的卤素原子或三氟甲基基团。该方法包括在有机溶剂中,在催化剂和氨的存在下,通过氢还原氧肟的步骤。氧肟的通式表示为(2),其中R1如上所述,R2代表氢原子、烷基或芳基烷基。通过该方法,可以高产地生产三氟甲基苯基胺。
