Sodium Carbonate → HCID 86706972, compound

Participants

Reaction Steps

Hydroxylamine hydrochloride (278 mg, 4.00 mmol) and sodium carbonate (318 mg, 3.00 mmol) were added to a stirred solution of 3-[4-(morpholin-4-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-5-yl]benzonitrile (C34) (436 mg, 1.00 mmol) in ethanol (10 mL) and water (5 mL). The reaction mixture was heated at reflux for 2 hours, then concentrated in vacuo, poured into water (25 mL), and extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with saturated aqueous sodium chloride solution (25 mL), dried over sodium sulfate, filtered, and concentrated, affording the product as a white solid. Yield: 280 mg, 0.60 mmol, 60%. 1H NMR (400 MHz, DMSO-d6) δ 9.67 (s, 1H), 8.43 (s, 1H), 7.89 (br s, 1H), 7.72 (s, 1H), 7.64 (br d, J=7.8 Hz, 1H), 7.53 (br d, J=7.8 Hz, 1H), 7.46 (dd, J=7.6, 7.6 Hz, 1H), 5.89 (br s, ˜1.6H), 5.61 (s, 2H), 3.53-3.61 (m, 2H), 3.39-3.47 (m, 4H), 3.13-3.21 (m, 4H), 0.81-0.88 (m, 2H), −0.09 (s, 9H).
