4-Pyridinemethanamine → HCID 44413030, compound

Participants

Reaction Steps

4-(Aminomethyl)pyridine (100 μL, 0.974 mmol) is added dropwise to a solution of (4-fluorophenyl)-(2-isopropylamino-pyrimidin-4-yl)-carbamic acid 4-nitro-phenyl ester, 5, (334 mg, 0.812 mmol) in methylene chloride (8 mL) at room temperature. The orange solution is stirred at ambient temperature overnight. The reaction mixture is diluted with methylene chloride (50 mL) and washed with a 0.5 N aqueous solution of sodium hydroxide (2×50 mL) and water (50 mL), dried over sodium sulfate, filtered and concentrated to a yellow oil which is purified over silica (20% Et2O/CH2Cl2 to 100% EtOAc) to afford the desired product as a white solid: 1H NMR (300 MHz, CDCl3) δ 10.76 (br s, 1H), 8.61 (d, J=6.0 Hz, 2H), 7.93 (d, J=5.7 Hz, 1H), 7.34 (d, J=6.0 Hz, 2H), 7.29-7.16 (m, 4H), 5.43 (d, J=5.9 Hz, 1H), 5.02 (br s, 1H), 4.60 (d, J=5.5 Hz, 2H), 4.15 (br s, 1H), 1.15 (d, J=6.4 Hz, 6H); MS (ESI) m/z 381 (M+1).
