Reaction Steps
46.9 g (330 mmol) of methyl cyclopentanone-2-carboxylate and 53.5 g (192 mmol) of S-methylisothiourea sulfate were successively added to 29.6 g (528 mmol) of KOH in 396 ml of methanol, and the mixture was stirred at room temperature overnight, acidified with 1N hydrochloric acid and diluted with water. The crystals which separated out were filtered off with suction and dried. 20 g of crystals were obtained.
