摘要
7-氯-5-氧代-2,3,4,5-四氢-1H-苯氮(?)经酰化、还原得到1-(4-氨基-2-甲基苯甲酰基)-7-氯-5-氧代-2,3,4,5-四氢-1H-1-苯氮(?),再经邻甲基苯甲酰氯酰化、硼氢化钠还原制得选择性精氨酸加压素V_2受体拮抗剂托伐普坦,总收率约45%。
Tolvaptan,a selective nonpeptide arginine vasopressin V_2 receptor antagonist,was synthesized from 7-chloro-5-oxo-2,3,4,5-tetrahydro-1H-1-benzazepine by acylation and reduction to give 1-(4-amino-2-methylbenzoyl) -7- chloro-5-oxo-2,3,4,5-tetrahydro-1H-1-benzazepine,which was subjected to acylation with 2-methylbenzoyl chloride and reduction with sodium borohydride with an overall yield of about 45%.
