Reaction Steps

A mixture of 1-(4-chlorobutyl)-5-(thiophen-2-yl)pyrimidine-2,4(1H,3H)-dione (Prep23, 50 mg, 0.18 mmol), 5-chloro-2,3-dihydrospiro[indene-1,3′-pyrrolidine]hydrochloride (Prep10, 66 mg, 0.27 mmol), potassium carbonate (112 mg, 0.81 mmol), sodium iodide (108 mg, 0.72 mmol) and NMP (1 ml) was stirred at 70° C. overnight. Then it was cooled down to room temperature and diluted with water and extracted with ethyl acetate. The EA phase was evaporated and the crude purified by preparative TLC (TLC analysis performed by eluting with EA) to give the free base of the title compound (72 mg). The compound was purified by preparative HPLC and treated with a 1N solution of HCl-ether and freeze-dried give the title compound (51 mg, y=58%).
