Iodoethane → 4-(Diethylamino)-2-ethoxybenzaldehyde

関与物質

反応手順

To a mixture of 2-hydroxy-4-(diethylamino)benzaldehyde (10.0 g, 51.75 mmol), K2CO3 (14.3 g) and DMF (150 ml) at room temperature was added ethyl iodide (4.1 ml). The reaction mixture was stirred for about two days, filtered and the filtrate was concentrated in vacuo. The residue was partitioned between ether and saturated Na2CO3, and the organic layer was separated, dried over MgSO4, treated with charcoal, filtered and concentrated in vacuo. The solid product was recrystallized from hexane to afford, as a pink crystalline solid, 9.8 g of 2-ethoxy-4-(diethylamino)benzaldehyde, m.p. 58°-59° C.
