Reaction Steps

A reaction mixture of 4-amino-6-chloro-pyrimidin-5-ol (1000.0 mg; 6.8 mmol; 1.0 eq.), cesium carbonate (2686.3 mg; 8.24 mmol; 1.2 eq.), and iodoethane (1285.9 mg; 8.24 mmol; 1.2 eq.) in acetone (10 ml) was stirred at 50° C. overnight. The reaction solution was diluted with ethyl acetate (50 ml), washed with water, then brine, dried and concentrated. The residue was treated with ether, stirred for 30 min, filtered, collected white off solid as title compound (1165 mg in yield 98%).
