Reaction Steps
To a solution of 4-hydroxy-3-methylbenzaldehyde (10 g, 73.5 mmol) in dry CH2Cl2 (550 mL) under nitrogen at 5° C. was added tetra-N-butylammonium borohydride (20.58 g, 80 mmol) and the resultant mixture stirred for 1.25 h at 5° C. Saturated ammonium chloride solution (30 mL) was added to the reaction mixture and the resultant mixture stirred for 1 h at 5° C. Saturated ammonium chloride solution (60 mL) was added and the reaction mixture extracted with CH2Cl2, dried (Na2SO4) and the solvents removed in vacuo. Purification by flushing through silica (2×150 g) eluting with EtOAc afforded the title compound as an oily yellow solid (8.01 g).
