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), 3-(2-formyl-5-isopropyl-1H-pyrrol-3-yl)-propionic acid (54.4 mg, 0.26 mmol) and piperidine (3 drops) in ethanol (2 mL) was stirred at room temperature for 2 days. The precipitate was collected by vacuum filtration, washed with water, 1N HCl, water and finally ethanol, dried in vacuum oven to give 83 mg (71%) of the title compound. 1H NMR (300 MHz, DMSO-d6) δ 13.44 (br s, 1H, NH), 12.15 (br s, 1H, COOH), 11.69 (br s, 1H, NH), 9.02 (br s, 1H), 8.29 (s, 1H), 7.77 (dd, J=2.5 & 6.4 Hz, 1H), 7.47 (s, 1H), 7.43 (m, 1H), 7.33 (t, J=8.9 Hz, 1H), 6.14 (d, J=2 Hz, 1H), 3.01 (m, 1H, CH(CH3)2), 2.83 (t, J=7.2 Hz, 2H, CH2), 2.48 (m, 2H, CH2), 1.21.27 (d, J=6.8 Hz, 6H, CH(CH3)2). MS 469 [M++1].
