Reaction Conditions

Reaction Steps

To a stirred suspension of sodium methoxide (3.48 g) in methanol (40 mL), cooled to 0° C., was added thiourea (3.56 g). The mixture was stirred until it dissolved, then 6-benzyloxy-3-oxo-hexanoic acid ethyl ester (8.52 g in 20 mL methanol) was added slowly. The solution was heated at reflux overnight, cooled to room temperature, and concentrated under vacuum. The residue was dissolved in water (50 mL), acidified to pH 6 with acetic acid, and stirred for 1 h. The precipitate was filtered, washed successively with water (2×20 mL) and isopropanol (2×20 mL), then dried to afford 6-(3-benzyloxy-propyl)-2-mercapto-pyrimidin-4-ol as a white powder (7.94 g). MS m/z 277.1 (M+1), 100%.
