Reaction Steps

The product from (e) (2 g) was heated with pyridine hydrochloride (20 g) at 170°-180° C. for 6 hours. The mixture was cooled, diluted with dilute hydrochloric acid, and extracted with ether. The ether extracts gave an oily solid which was purified by preparative thin layer chromatography using silica as the adsorbent and 6% ethanol-chloroform as the solvent.
