反応手順

2-Hydroxy-1-naphthaldehyde (10 g., 0.058 mole) was combined with acetone (120 ml.), iodoethane (9.9 g., 0.063 mole) and anhydrous potassium carbonate (8.0 g., 0.058 mole) and the mixture heated to reflux for 48 hours. The reaction mixture was cooled to room temperature, filtered and filtrate evaporated to solids (9.0 g.) Recrystallization from isopropyl ether afforded purified 2-ethoxy-1-naphthaldehyde in two crops (4 5 g. and 0.5 g., m.p. 106°-109° C.).
