Sodium Methoxide → {2-Methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-methanol

Participants

Reaction Steps

A mixture of {2-chloro-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-methanol (6.5 g mg, 22.1 mmol, Intermediate (57)] 25 wt % sodium methoxide in MeOH (15.2 mL, 66.3 mmol), in MeOH (20 mL) is heated to 90° C. and stirred for 3 hours and concentrated by rotary evaporator to remove the solvent. The solid is dissolved in water and the solution is acidified to pH 8 with the addition of saturated ammonium chloride solution. Extracted twice with 150 mL ethyl acetate, combined the extracts, Dried over magnesium sulfate, filtered and concentrated to afford {2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-methanol [5.6 g, 88%, Intermediate (58)] as a solid. LCMS: RT=2.35 minutes, MS: 290 (M+H).
