The quick results cold capsule has almost become a family during the past the past few years must prepare for medicines and chemical reagents , many people has coughed , cephalea , stream mucus , pharyngalgia have all taken it, be much used for preventing the cold , incorrect from being even.

近几年来速效感冒胶囊险些成了家庭必备药品，许多人咳嗽、头痛、流涕、咽痛都服用它，以致还常用来预防感冒，这是错误的。本品大剂量服用会引起中毒相应，以致危及生命。曾有人一次服用7粒速效感冒胶囊发生马来酸氯苯即敏中毒，经救济才脱险。速

The synthetic route starts from penicillin G, peroxyacetic acid(8.5%) as Oxidizing Agent to get penicillin G sulfoxide; esterifided with p-nitrobenzyl bromine to synthesize penicillin G sulfoxide ester; we synthesize 3-exomethylenecepham sulfoxide ester with phthalimide potassium and 4A molecular sieve as acid scavenger to open the ring, SnCl_4 as catalyzation to close the ring. The yield is over 60%.
