Reaction Steps

10 g of 2-mercaptopyridine, 14.2 g of 4-nitrophthalonitrile, and 22.6 g of potassium carbonate were suspended in 250 ml of acetone and heated at reflux temperature for 4 hours. The solution was filtered through a pad of celite and a course glass filter to remove residual solids. The solution was concentrated to a crude residue and purified by column chromatography on silica gel eluting the product with a gradient of 0-10% ethyl acetate in dichloromethane. 6.4 g of product was recovered; 1H NMR (200Mz, CDCl3) δ=8.49-8.53 (m, 1H), 7.84-7.83 (dd, 1H), 7.76-7.71 (m, 2H), 7.68-7.64 (dd, 1H), 7.40-7.36 (dt, 1H), 7.27-7.20 (m, 1H).
