実験手順

A solution of 8-bromo-naphthalene-1-carboxylic acid (1.6 g) in DMF (15 ml) was treated with potassium carbonate (2.2 g) and iodoethane (1.03 ml). The reaction mixture was stirred overnight at r.t., then quenched with water and extracted with ethyl acetate. The organics were dried over MgSO4, filtered and concentrated. The crude product was purified by column chromatography (silica gel; gradient: cyclohexane→cyclohexane/EtOAc 1:1) to give 8-bromo-naphthalene-1-carboxylic acid ethyl ester (1.57 g) as colorless liquid. MS (ISP): 279.1 ((M+H)+.).
