Reaction Steps
To a solution of 1.18 g (6.76 mmol) 2-chloro-5-methoxy-3-methylpyrimidin-4(3H)-one in 35 ml CH2Cl2 was added 47.3 ml (47.3 mmol) of a 1 M solution of BBr3 in CH2Cl2. The reaction mixture was stirred for 1 h, cooled to 0° C., quenched with 100 ml MeOH, and concentrated in vacuo. The solid was suspended in ether, and collected by filtration to give 1.09 g (100% yield) of 2-chloro-5-hydroxy-3-methylpyrimidin-4(3H)-one. LCMS [M+H]+=161.0.
