実験手順

A mixture of anisaldehyde (350 μL, 2.87 mmol, 1.0 equ.), malononitrile (190 mg, 2.87 mmol, 1.0 equ.) and triethylamine (400 μL, 2.87 mmol, 1.0 equ.) in ethanol (10 mL) was stirred for 1 min, followed by the addition of 3-(4-methoxyphenyl)-1-phenyl-1H-pyrazol-5(4H)-one (764 mg, 2.87 mmol, 1 equ.). The reaction mixture was concentrated after 24 h and the precipitate was washed with ethanol and hexanes, and then re-crystallized from ethanol to give 6-amino-3,4-bis(4-methoxyphenyl)-1-phenyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (1.06 g, 2.35 mmol, 82%) as a white solid. 1H-NMR (400 MHz) DMSO: 7.93-7.91 (d, 2H), 7.56-7.52 (m, 4H), 7.38-7.35 (t, 1H), 7.15-7.11 (m, 4H), 6.83-6.78 (m, 4H), 4.98 (s, 1H), 3.70 (s, 3H), 3.66 (s, 3H), 13C-NMR (100 MHz) DMSO: 159.5, 158.9, 158.4, 146.6, 145.5, 137.9, 136.6, 129.8, 129.0, 128.3, 127.0, 125.2, 121.0, 120.4, 114.2, 114.1, 97.7, 60.3, 55.5, 55.3, 37.1; LC/MS-MS: 452.3→89.1 m/z; GS1 and GS2 at 30, DP=36, CE=39, CXP=4, tR=3.47 min.
