To a solution of 789 mg of tert-butyl (2E)-3-[2-(hydroxymethyl)-3-methylphenyl]acrylate in 16 ml of methanol was added 82 mg of nickel chloride (II). Then, 240 mg of sodium borohydride was added thereto under ice-cooling, followed by stirring for 4 hours under ice-cooling. To the reaction mixture were added water and ethyl acetate to carry out a layer separation operation. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to obtain 790 mg of tert-butyl 3-[2-(hydroxymethyl)-3-methylphenyl]propanoate.
