Reaction Steps

The compound (4.0 g, 10 mmol) of example 34 was suspended in ethanol (10 ml), and added with ethyl isothiocyanate (0.9 g, 1.1 mmol) and triethylamine (1 mL). After refluxed for 3 h, the reaction mixture was concentrated to dryness. The resultant solid was washed with distilled water and recrystallized from ethyl acetate-petroleum ether to give the title compound (3.4 g, yield: 74%). 1H NMR (DMSO-d6) δ: 12.38 (1H, br), 9.41 (1H, br), 7.74 (1H, d), 7.54 (1H, dd), 7.15 (1H, d), 4.04 (2H, t), 3.46 (2H, m), 3.37 (1H, m), 1.75 (2H, m), 1.18 (6H, d), 1.11 (3H, t), 0.97 (3H, t).
