Cyclohexylamine → HCID 18446572、化合物

To a solution of 4-chloro-7-cyano-2-(4′-t-butylphenyl)-thieno[3,2-c]pyridine (0.05 g, 0.153 mmol) in DMF was added cyclohexylamine (0.017 g, 0.168 mmol) and potassium carbonate (0.023 g, 0.168 mmol). The resulting mixture was stirred under nitrogen at 80° C. for 2 h. After this time the mixture was partitioned between ethyl acetate (10 mL) and saturated aqueous sodium bicarbonate solution (10 mL), and the organic layer washed with water and brine, then dried over magnesium sulphate and concentrated under reduced pressure. Purification by silica gel chromatography (eluent 20% ethyl acetate in hexane) afforded 0.042 g of 102. 1H NMR (400 MHz, CDCl3) δ 8.27 (s, 1H), 7.63 (d, 2H), 7.50 (d, 2H), 7.38 (s, 1H), 5.14 (bs, 1H), 4.20 (bs, 1H), 2.18 (m, 2H), 1.80 (m, 4H), 1.6-1.12 (m, 13H).
