A solution of mesitylacetonitrile (66 mg, 0.41 mmol) in 1 ml of DMSO was treated with NaH (60% in oil, 20 mg 0.50 mmol) and stirred at room temperature for 20 minutes, butyl-(6-chloro-2,5-dimethylpyrimidin-4-yl)-ethylamine (100 mg, 0.414 mmol) was added and the resulting mixture was heated at 130° C. for 15 hours. The mixture was quenched with water and extracted with ethyl acetate. The organic layer was separated, dried and concentrated to give 160 mg of brown oil. The oil was purified through silica gel column chromatography using 5% ethyl acetate in hexane as eluent to give the title compound as a brown oil. 1H NMR (CDCl3) δ 6.83 (s, 2H), 5.49 (s, 1H), 3.2-3.4 (m, 2H), 3.0-3.2 (m, 2H), 2.51 (s, 3H), 2.24 (s, 3H), 2.21 (s, 6H), 1.66 (s, 3H), 1.35-1.50 (m, 2H), 1.1-1.3 (m, 2H), 1.05 (t, 3H), 0.84 (t, 3H) ppm.
