To a solution of 2-methanesulfonyl-pyrimidine-5-carboxylic acid methyl ester (0.8 g, 3.7 mmol) in NMP (3 mL) is added sodium phenoxide trihydrate (0.68 g, 4 mmol). The mixture is heated at 100° C. in Biotage Microwave for 60 sec. The reaction is poured into water and the precipitate is collated by filtration and dried to afford 2-phenoxy-pyrimidine-5-carboxylic acid methyl ester (0.56 g, 66%) as a solid. MS: 231 (M+H); 1H NMR (300 MHz, CDCl3): δ 4.75 (s, 3H), 7.19-7.33 (m, 3H), 7.46 (t, 2H) 9.10 (s, 2H).
