Reaction Steps
To a mixture of the acid chloride 45 (0.6 g, 2.45 mmol) and 3-aminopropylcyanide hydrochloride (0.31 g, 2.57 mmol) in anhydrous toluene was added 1.5 ml of anhydrous pyridine. The reaction mixture was stirred at 50° C. overnight and then evaporated to dryness. The product was purified by chromatography using toluene-ethyl acetate (2:1) to yield white crystals (0.623 g, 87%). 1H NMR (DMSO-d6) δ 8.46 (t, 1H), 8.17 (d, 1H), 7.39 (d, 1H), 4.37 (t, 2H), 3.27 (quintet, 2H), 2.53 (d, 2H), 1.77 (quintet, 2H), 1.60–1.42 (q and quintet, 3H), 0.87 (d, 6H).
