We describe an efficientprocess for the preparation of tazarotene starting from 4,4-dimethyl-6-bromothiochromane S-oxide (9), 2-methyl-3-butyn-2-ol (10), and 6-chloronicotinic acid ethyl ester (8). Our synthetic pathway compares favorably over the previously reported procedures since tazarotene was prepared straightforwardly using cheap reagents and without the employment of hazardous organometallic
