Reaction Steps

A mixture of 2-chloro-4-(5-tosylthiophen-2-yl)pyrimidine (100 mg, 0.23 mmol), 1-(2-aminoethyl)-5,5-dimethylimidazolidine-2,4-dione (33 mg, 0.26 mmol) and triethylamine (28 mg, 0.27 mmol) in toluene (3 mL) was heated at 160° C. for 35 min in a Personal Chemistry microwave reactor. Upon cooling to rt the precipitate was filtered and washed with diethyl ether. The solid was put into 2 mL of methanol and the suspension was stirred for about 15 min and filtered to afford the title compound as pale yellow crystals (56 mg, 50%). MS (M+H)+ 486.
