隣苯二甲醯亚胺钾与1.4-二溴戊烷制成的4-溴-1-隣苯二甲醯亚氨基戊烷,与6-甲氧基-8-氨基喹啉共熔后,再行水解得伯氨喹啉。双磷酸伯氨喹啉总产率按所用隣苯二甲醯亚胺钾计算为42.5—48.4％。
4-bromo-1-o-phthalidinimidopentane prepared from potassium phthalimide and 1.4-dibromopentane, and after eutectic melting with 6-methoxy-8-aminoquinoline, Subsequent hydrolysis of primary aminoquinoline. The total yield of primaquine bisphosphonates was calculated to be 42.5 to 48.4% based on the potassium phthalimide used.
