To a solution of 6-(4-nitrophenylmethyl)-3-methyl-1-(2-methylpropyl)thieno[2,3-d]pyrimidin-2,4(1H,3H)-dione (275 mg) in ethanol (15 ml) and water (1 ml) was added iron powder (82 mg) and ammonium chloride (78 mg). The mixture was heated at 90° C. for 6 h. and then allowed to cool to room temperature. The reaction was filtered and then evaporated before being partitioned between ethyl acetate and water. The organic layer was collected, dried over magnesium sulfate, and then evaporated. The resultant oil was purified by normal phase HPLC (isohexane:ethyl acetate 80-0:20-100) to give the title compound (20 mg).
