Potassium Carbonate → HCID 178418728, compound

Participants

Reaction Steps

To a solution of 2-chloro-4-(4-methylpiperidin-1-yl)-pyrimidine (prepared using a procedure similar to the one reported in Eur. J. Med. Chem., 26(7) 729(1991))(222 mg, 1.05 mmol) in BuOH (5 mL) was added 3-amino-5-methyl-2H-pyrazole (305 mg, 3.15 mmol) and the reaction mixture was then heated under reflux overnight. The solvent was evaporated and the residue dissolved in a mixture ethanol/water (1/3, 4 mL). Potassium carbonate (57 mg, 0.41 mmol) was added and the mixture was stirred at room temperature for 2 hours. The resulting suspension was filtered, washed with water twice and rinsed with ether twice to give the title compound as a white solid (143 mg, 50%): mp 193–195° C.; 1H NMR (DMSO) δ 0.91 (3H, d), 1.04 (2H, m), 1.67 (3H, m), 2.16 (3H, s), 2.83 (2H, t), 4.31 (2H, m), 6.19 (2H, m), 7.87 (1H, d), 8.80 (1H, br s), 11.71 (1H, s); IR (solid) 1627, 1579, 1541, 1498, 1417, 1388, 1322, 1246; MS 273.3 (M+H)+.
