A mixture of 4-(3-chloro-4-fluoro-phenylamino)-7-methyl-5,7-dihydro-pyrrolo[2,3-d]pyrimidin-6-one (116 mg, 0.4 mmol), 3-methyl-5-(morpholine-4-carbonyl)-1H-pyrrole-2-carbaldehyde (130 mg) and piperidine (1 drop) in ethanol (2 mL) was stirred at 90° C. for 2 hours. The reaction was diluted with water and the precipitate was collected by vacuum filtration, washed with water, ethyl acetate and hexane and dried to give 141 mg (74%) of the title compound. 1H NMR (300 MHz, DMSO-d6) δ 13.42 (br s, 1H, NH), 9.29 (br s, 1H), 8.38 (s, 1H), 7.72 (m, 1H), 7.34-7.41 (m, 3H), 6.6 (s, 1H), 3.67 (m, 4H, 2×CH2), 3.65 (m, 4H, 2×CH2), 3.29 (s, 3H, CH3), 2.20 (s, 3H, CH3). MS 497 [M++1].
