Procedure

A mixture of 1-(4-chlorobutyl)-5-(thiophen-2-yl)pyrimidine-2,4(1H,3H)-dione (Prep23, 50 mg, 0.18 mmol), 5-fluoro-2,3-dihydrospiro[indene-1,3′-pyrrolidine]hydrochloride salt (Prep14, 50 mg, 0.26 mmol), potassium carbonate (108 mg, 0.78 mmol), sodium iodide (108 mg, 0.72 mmol) and NMP (1 ml) was stirred at 70° C. overnight. The mixture was then diluted with water and extracted with ethyl acetate. The EA phase was evaporated and the crude purified by preparative TLC 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 to give the title compound (30 mg, y=35%).
