Reaction Steps

(Step 2) To a mixed solution of 3-chloro-5-cyanobenzoate (1.13 g) obtained in Step 1 in tetrahydrofuran:ethanol=10:1 (33 ml) was added lithium tetrahydroborate (0.19 g) at 0° C. After stirring at 60° C. for 2 hr, the reaction solution was quenched with ice and extracted with ethyl acetate. The extract was washed with 1N hydrochloric acid and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was treated by silica gel chromatography (ethyl acetate:hexane=1:1) to give 3-chloro-5-(hydroxymethyl)benzonitrile (0.60 g) as a white solid.
