Ethyl 4-(4-((4-(tert-butoxycarbonyl)piperazin-1-yl)methyl)phenylamino)-6-methyl-2-morpholinopyrimidine-5-carboxylate (350 mg, 0.64 mmol) was dissolved in DMF (5 mL), dimethyl formamide dimethyl acetal (0.26 mL) was added and the mixture was heated to 130° C. for 12 hours. The reaction mixture was poured into water and extracted with EtOAc. The organic layer was washed with water, dried over Na2SO4 and evaporated to give the desired product (0.23 g). 1H NMR (400 MHz, DMSO-d6): δ 10.44 (s, 1H), 7.94 (d, J=12.2 Hz, 1H), 7.55 (d, J=8.8 Hz, 2H), 7.22 (d, J=8.8 Hz, 2H), 5.89 (d, J=12.2 Hz, 1H), 4.30 (q, J=6.8 Hz, 2H), 3.80 (s, 2H), 3.75-3.65 (m, 8H), 3.33 (m, 4H), 3.32 (m, 6H), 2.41 (m, 4H), 1.38 (s, 9H), 1.32 (t, J=6.8 Hz, 3H); MS m/z 596.4 (M+1).
