Reaction Steps

In a 25 ml RBF, a mixture of 5-chloro-2-fluorobenzaldehyde (505 mg, 3.09 mmol), 3-methyl-1H-1,2,4-triazole (270 mg, 3.09 mmol), Cs2CO3 (1007 mg, 3.09 mmol) in DMSO (6179 μl) was heated at 45° C. for 4 hrs and stirred at rt overnight. The reaction mixture was diluted with EtOAc and washed with water. The combined organic phase was washed with brine, dried over MgSO4, filtered, concentrated and purified by flash chromatography to yield 74A as white solid product (140 mg, 20%). 1H NMR (400 MHz, DMSO-d6) δ ppm: 9.95 (s, 1H), 9.02 (s, 1H), 7.96-7.88 (m, 2H), 7.80 (d, J=8.4 Hz, 1H), 2.37 (s, 3H).
