Reaction Steps

A mixture of 4-(3-chloro-4-fluoro-phenylamino)-5,7-dihydro-pyrrolo[2,3-d]pyrimidin-6-one (70 mg, 0.25 mmol), 5-(4-ethyl-piperazine-1-carbonyl)-3-methyl-1H-pyrrole-2-carbaldehyde (74.8 mg, 0.3 mmol) and piperidine (3 drops) in ethanol (2 mL) was stirred at room temperature for overnight. The precipitate was collected by vacuum filtration, washed with ethanol and dried to give 93 mg (73%) of the title compound. 1H NMR (300 MHz, DMSN d6) δ 3.40 (br s, 1H, NH), 11.81 (br s, 1H, NH), 9.28 (br s, 1H), 8.33 (s, 1H), 7.72 (m, 1H), 7.33-7.45 (m, 3H), 6.58 (m, 1H), 3.68 (m, 4H, 2×CH2), 2.31-2.42 (m, 6H), 2.22 (s, 3H, CH3), 1.01 (t, J=7.2 Hz, 3H, CH2CH3). MS 510 [M++1].
