実験手順

A solution of ethyl 6-methyl-2-(trifluoromethyl)pyrimidine-4-carboxylate (2.00 g, 8.54 mmol, prepared as described in WO2007/090748) in acetic acid (12 mL) was treated with bromine (1.36 g, 8.54 mmol) and the reaction was heated to 80° C. in a sealed vial for 30 minutes, at which time it was decolorized. The mixture containing unreacted starting material, desired product, and over brominated product, was rotovapped and azeotroped once with toluene. The percent by weight of desired component was determined by NMR and the mixture used without further purification. Yield: 1.62 g (61%); LC-MS: 313.0, 315.0 (M+H)+. 1H NMR (300 MHz, CDCl3): δ 8.32 (s, 1H), 4.60 (s, 2H), 4.54 (q, 2H), 1.46 (t, 3H).
