补充资料：1-(对-叔丁苄基)-4-(对-氯代二苯甲基)哌嗪
分子式：C28H33ClN2
分子量：433.04
CAS号：82-95-1
性质：白色粉末结晶。熔点230-240℃（221-225℃）。不溶于水，溶于乙醇、氯仿，沸点217-220℃（0.133千帕）。其盐酸盐（C28H33CIN2·2HCI=505.98）也称安其敏，熔点265-266℃。
制备方法：以叔丁醇为原料，在三氯化铝存在下，与苯反应生成叔丁苯，用多聚甲醛、盐酸等做氯甲基化反应，生成对-叔丁基苄氯，然后与哌嗪缩合生成对-叔丁基苄基哌嗪盐酸盐，用碱中和得对-叔丁基苄基哌嗪，与对-氯二苯溴甲烷缩合，生成氯苯丁嗪，最后与盐酸成盐。生成盐酸氯苯丁嗪[129-74-8]。
用途：抗过敏性药物。可用于荨麻疹、神经性皮炎等。亦可用于妊娠呕吐、晕动症。
