Hydrochloric Acid → 2,4-Dihydroxy-6-methoxymethyl-benzaldehyde

Participants

Reaction Steps

To a solution of 2,4-bis-methoxymethoxy-6-methoxymethyl-benzaldehyde (3.93 g, 14.45 mmol) in THF (30 mL) was added 6 N HCl (10 mL). The mixture was stirred at room temperature for 20 hours then diluted with EtOAc (200 mL). The mixture was washed with brine, dried and concentrated to give 2,4-dihydroxy-6-methoxymethyl-benzaldehyde (2.62 g, 100%). 1H NMR (400 MHz, CDCl3δ 12.40 (s, 1H), 10.10 (s, 1H), 6.41 (s, 1H), 6.30 (s, 1H), 5.60 (s, 1H), 4.61 (s, 2H), 3.40 (s, 3H).
