Reaction Steps

To a solution of 2.28 g (5 mmol) 5-bromo-2-methyl-pyrimidine-4-carboxylic acid 3,5-bis-trifluoromethyl-benzylamide in 20 ml N,N-dimethylformamide 0.26 g (5.5 mmol) sodiumhydride (60% dispersion in mineral oil) was added and the reaction mixture stirred for 1 hr. After the addition of 0.4 ml (6.5 mmol) methyl iodide at 0°, the reaction mixture was stirred for 3 hrs. at RT. The reaction mixture was distributed between 80 ml H2O, 80 ml brine and 80 ml CH2Cl2. The phases were separated, the aqueous layer washed twice with 80 ml CH2Cl2. The combined organic layers were dried (MgSO4), filtered and evaporated. The residue was purified by chromatography (SiO2, CH2Cl2/MeOH 19:1) to give 1.98 g (87%) 5-bromo-2-methyl-pyrimidine-4-carboxylic acid (3,5-bis-trifluoromethyl-benzyl)-methyl-amide as a waxy solid.
