Procedure

A mixture of methyl 2,4-dicyano-6-(m-tolylamino)pyrimidine-5-carboxylate (102.3 mg, 0.349 mmol), N,N-diisopropylethylamine (0.075 mL, 0.429 mmol) and cyclohexylamine (0.05 mL, 0.437 mmol) in DMF (2 mL) was stirred at RT for 14 h. Saturated aq NaHCO3 was added and the mixture was extracted with EtOAc. The organic layers were washed with aq NaHCO3, water, and brine, and were filtered through SiO2. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography (SiO2, hexanes/EtOAc=4/1) to give the title compound as a yellow oil (114.7 mg, 90%). 1H NMR (500 MHz, CDCl3) δ ppm 1.19-1.45 (m, 5H), 1.64-1.67 (m, 1H), 1.73-1.80 (m, 2H), 2.00-2.05 (m, 2H), 2.38 (s, 3H), 3.75-3.82 (m, 1H), 3.98 (s, 3H), 5.57-5.58 (br d, J=7.9 Hz, 1H), 6.97-6.98 (m, 1H), 7.27-7.29 (m, 1H), 7.46-7.51 (m, 2H), 10.62 (br s, 1H). [M+H] calc'd for C20H24N5O2, 366. found, 366.
