Reaction Steps

To a solution of acetamidine hydrochloride (0.617 g, 6.53 mmol) in methanol (10 mL) was added potassium tert.-butoxide (0.80 g, 6.54 mmol) followed by methyl 3-[1-(4-chlorophenyl)cyclobutyl]-3-oxopropionate (1.34 g, 5.02 mmol). The mixture was stirred at 20° C. for 16 h, then refluxed for 2 h. The reaction mixture was cooled, diluted with water, made alkaline by the addition of 10 mL of 10% aqueous sodium hydroxide solution, and then washed with diethyl ether. The aqueous phase was acidified with concentrated hydrochloric acid, and then extracted with diethyl ether. This ether extract was washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure to give the title compound (1.04 g, 75%) as a solid foam. Mp 130-140° C.
