実験手順

To a solution of 7-chloro-2-(2-chlorophenyl)-3-iodopyrazolo[1,5-a]pyrimidine (I-1A-1d; 80 mg, 0.21 mmol) and triethylamine (44 μl, 0.32 mmol) in 1:1 ethanol/methylene chloride (2 ml) was added 4-ethylaminopiperidine-4-carboxylic acid amide (I-1A-1g; 40 mg, 0.23 mmol). A colorless precipitate formed after several minutes and the mixture was stirred overnight. The solid precipitate was isolated by vacuum filtration, washed with ethanol and ether, and then dried, in vacuo, to afford product I-1A-1h as an off-white solid (95 mg, 86%): +APcI MS (M+1) 525.4; 1H NMR (400 MHz, CD3OD) δ 8.27 (d, J=5.4 Hz, 1H), 7.55 (d, J=7.5 Hz, 1H), 7.48–7.39 (m, 3H), 6.45 (d, J=5.6 Hz, 1H), 4.14–3.96 (m, 2H), 3.92–3.84 (m, 2H), 2.50 (q, J=7.1 Hz, 2H), 2.23–2.15 (m, 2H), 1.85–1.77 (m, 2H), 1.16 (t, J=7.1 Hz, 3H).
