Reaction Conditions

Reaction Steps

To 684 mg (3 mmol) of 4-benzyloxy-3-methyl-phenol in 10 mL toluene and 1.5 mL DME (dimethoxyethane) in a sealable tube was added paraformaldehyde (1.8 g, 60 mmol). The tube was flushed with argon and sealed. It was heated to 130° C. for 48 h under stirring. After cooling to room temperature, the solid was filtered off and washed with 1:1 hexane/EtOAc and the liquid was concentrated. The residue was chromatographed to afford 4-benzyloxy-6-hydroxymethyl-2,3-dimethyl-phenol, as a light brown solid (640 mg). 1H-NMR (300 MHz, CDCl3/CD3OD)) δ (ppm): 7.43-7.29 (m, 5H), 6.55 (s, 1H), 4.95 (s, 2H), 4.70 (s, 2H), 2.18 (s, 3H), 2.16 (s, 3H); MS (ESI) m/z: 241 (M−OH−, 100%).
