A 1-alkyl-1,2,4,5-tetrahydro-3H-1,4-benzodiazepine derivative is produced by contacting a 1-aminoethyl-indole derivative with a suitable oxidizing agent and then reducing the resulting 1-acyl-2,3-dihydro-1H-1,4-benzodiazepine derivative. The starting 1-aminoethyl-indole derivative is prepared by subjecting a 3-phenyl-indole derivative to cyanomethylation (or carbamoylemethylation) and then reducing the resulting 1-cyanomethyl- (or 1-carbamoylmethyl)-indole derivative. The 1-acyl-1,2,4,5-tetrahydro-3H-1,4-benzodiazepine derivative is useful as a tranquillizer, muscle-relaxant, etc.
通过将1-氨基乙基吲哚衍生物与适当的氧化剂接触,然后还原所得的1-酰基-2,3-二氢-1H-1,4-苯二氮平衍生物,可以制备出1-烷基-1,2,4,5-四氢-3H-1,4-苯二氮平衍生物。起始的1-氨基乙基吲哚衍生物是通过将3-苯基吲哚衍生物经过氰甲基化(或者氨基甲酰化)然后还原所得的1-氰甲基-(或1-氨基甲酰基)-吲哚衍生物制备的。所得的1-酰基-1,2,4,5-四氢-3H-1,4-苯二氮平衍生物可用作镇静剂、肌肉松弛剂等。
