Abstract

Warming a title acid with SOCl2 gives the corresponding 3,3,9- trichlorothieno[3,4-b]quinolin-1(3H)-one whereas reaction at room temperature leads to the intermediate 3,3-dichloro-4-ethylthieno[3,4-b]quinoline- 1(3H),9(4H)dione product as established from the respective X-ray crystallographic determinations.
