실험 절차

A solution of 6-cyano-naphthalene-2-carboxylic acid methyl ester from Example 96 (2.00 g, 9.47 mmol) in THF (19 mL) and 1M aqueous LiOH (18.94 mL, 18,94 mmol) was vigorously stirred at room temperature for 3 hours. The reaction mixture was then diluted with 150 mL of 1:1 dichloromethane/water, and the organics were discarded. The aqueous material was acidified to pH 2 with 1N HC1, extracted with EtOAc (2×150 mL), extracts dried over MgSO4, and concentrated to provide the desired compound as a white solid (1.61 g, 86%).
