実験手順

A mixture of 4-chloro-3,6-dimethyl-1-(2,4,6-trimethylphenyl)-1H-pyrazolo[3,4-b]pyridine (98 mg, 0.33 mmol), N-butylethylamine (1 ml) in DMSO (2 ml) was heated in an oil bath at 175-180° C. for 20 hours. The reaction mixture was quenched with saturated ammonium chloride and extracted with EtOAc. The organic layer was washed with brine, dried, and concentrated to give a brown oil. The oil residue was purified through silica gel column chromatography using EtOAc/Hexane in a ratio of 1/9 as eluent to give a colorless oil. 1H NMR (CDCl3) 6.92 (s, 2H), 6.29 (s, 1H), 3.42 (q, 2H), 3.27 (t, 2H), 2.65 (s, 3H), 2.44 (s, 3H), 2.30 (s, 3H), 1.91 (s, 6H), 1.57 (m, 2H), 1.33 (m, 2H), 1.13 (t, 3H), 0.90 (t, 3H) ppm. IR (neat) 2960, 2920, 1570 cm−1. High MS, calc. 364.2627, found 364.26306.
