Reaction Steps

To an ice-cooled solution of 5-fluoro-N, 2-dimethyl-N′-((6-(pyridin-3-yl)imidazo[1,2-a]pyridin-3-yl)methylene) benzenesulfonohydrazide (step 1, 18 mg, 0.043 mmol) in CH2Cl2 was added 3-chloroperoxybenzoic acid (14.46 mg, 0.065 mmol). The reaction mixture was stirred for 3 h at RT. The reaction mixture was then poured on to water. Organic layer was separated, washed with saturated solution of NaHCO3 and dried over Na2SO4. Crude compound was purified by column chromatography (silica gel, 5% EtOAc in petroleum ether) to obtain the title compound. Yield: 64%; 1H NMR (DMSO-d6; 300 MHz,): δ 9.45 (s, 1H), 8.57 (s, 1H), 8.32-8.31 (m, 2H), 8.03 (s, 1H), 7.83-7.79 (m, 2H), 7.67-7.64 (dd, 1H, J=8.4 Hz, 2.4 Hz), 7.56 (m, 1H), 7.43-7.36 (m, 3H), 3.40 (s, 3H), 2.54 (s, 3H); MS: m/z 440 (M+1)+.
