Reaction Steps

To ethanol (20 ml) was added sodium ethoxide solution (7.76 ml of a 21% wt solution in ethanol), 4-chlorobenzamidine hydrochloride (1.0 g) and diethylmethylmalonate (0.89 ml). The suspension was stirred at 40° C. in an inert atmosphere for 44 hrs after which time it was cooled to 5° C. and treated dropwise with concentrated hydrochloric acid to a pH of 2. The resulting suspension was filtered and washed with excess water, then ethanol (20 ml) and diethyl ether (20 ml) affording the title compound as a solid (1.71 g).
