N-(2-naphthylformyl)-N-(5-methylpyridin-2-yl)-2-naphthamide (2.91 g, 6.99 mmol) was dissolved in ethanol (50 mL) and 85% hydrazine hydrate (5 mL), and stirred at room temperature for 8 hours. It was concentrated under reduce pressure, chromatographed on a silica gel column (petroleum ether:ethyl acetate=3:1) to obtain a white solid 1.8 g, at a yield of 98.1%.
