摘要 以4-甲氧羰基哌啶盐酸盐(1)和对三氟甲氧基苯甲酰氯(2)为起始原料,在三乙胺的作用下以92.7%的收率制得1-(4-三氟甲基苯甲酰基)-4-甲氧羰基哌啶(3);化合物(3)在羰基二咪唑与N,O-二甲基羟胺盐酸盐(4)作用下,以89.9%的收率制得1-(4-三氟甲氧基苯甲酰基)-4-(N-甲基-N-甲氧基羰基)哌啶(5);化合物(5)和4-甲氧基苯基溴化镁(6)偶联,以60.1%的收率制得化合物1-(4-三氟甲氧基苯甲酰基)-4-(4-甲氧基苯甲酰基)哌啶(7)。三步反应总收率50.0%。 Methylisonipecotah( 1 ) and 4-trifluromethoxylbenzoyl chloride(2) reacted in DCM in the presence of triethylamine to form 1-( 4-trifluromethoxylbenzoyl ) -4-( methoxycarbonyl ) piperidine ( 3 ) with 92.7% yield. The compound ( 3 ) then treated with N, O-dimethylhydroxylamine hydrochloride (4) was converted into 1-( 4-trifluromethoxylbenzoyl ) -4-( N-methyl-N-methoxycarbonyl ) piperidine ( 5 ) with 89.9 % yield, the compound ( 5 ) then coupled with 4-methoxyphenyl magnesium bromide (6) to obtain 1 - (4-trifluromethoxylbenzoyl) -4-(4-methoxylbenzoyl) piperidine (7) with 60.1% yield. The overall yield of three steps was 50.0%.
