Reaction Steps
Into a reaction vessel was charged sodium hydride (4.8 g, 0.12 mol) and N,N′-dimethylformamide (40 ml), and a solution obtained by dissolving 4-cyano-2-hydroxytoluene (14) (13.3 g, 0.1 mol) in N,N′-dimethylformamide (40 ml) in an ice bath was dropped on this, and the solution was stirred for 1.0 hour at room temperature. Subsequently, ethyl iodide (18.7 g, 0.12 mol) was dropped in an ice water, and the solution was stirred for 1.5 hours at room temperature. To the reaction liquid was added water and extracted with ethyl acetate, then, washed with saturated saline, dried, and the solvent was distilled off under reduced pressure, to obtain 4-cyano-2-ethoxytoluene (15) (16.1 g, yield from (14) is 99%).
