| Synthesis | General procedure for the synthesis of 2-amino-4-methyl-5-bromopyrimidine from 2-amino-4-methylpyrimidine: To a solution of 4-methylpyrimidin-2-ylamine (10.9 g, 100 mmol) in chloroform (400 mL) was added N-bromosuccinimide (17.8 g, 100 mmol). The reaction mixture was stirred under light-avoiding conditions for 15 hours. Upon completion of the reaction, the mixture was transferred to dichloromethane (140 mL) and washed sequentially with 1N sodium hydroxide solution (3 x 200 mL) and saturated sodium chloride solution (100 mL). The organic phase was dried with anhydrous sodium sulfate, filtered and concentrated to give 5-bromo-4-methylpyrimidin-2-ylamine (18.8 g, 99% yield). The product was detected by LCMS (m/z): 188.0/190.0 (MH+). 1H NMR (CDCl3) data: δ 8.22 (s, 1H), 5.02 (bs, 2H), 2.44 (s, 3H). | | References | [1] Patent: WO2007/84786, 2007, A1.
