Reaction Steps

A solution of 2-(4-fluorophenyl)pyrazolo[1,5-a]pyridine-6-carbonitrile (0.6 g 2.53 mmol) and NBS (0.5 g 2.8 mmol) in DMF (10 ml) was stirred at room temperature for 2 hr. The reaction was poured into water (100 ml) and extracted with ethyl acetate (2×30 ml). The combined extracts were washed with water (30 ml), brine (30 ml), dried and purified by biotage chromatography. Elution with cyclohexane/ethyl acetate (20:1) gave the title compound as a white solid (0.483 g 61%). NMR: (CDCl3): δ 7.21 (2H, t) 7.30 (1H, dd) 7.62 (1H, dd) 8.06 (2H, m) 8.80 (1H, s).
