Methyl 3-(benzyloxy)-5-[(1S)-2-methoxy-1-methylethoxy]benzoate → methyl 3-hydroxy-5-[(1S)-2-methoxy-1-methylethoxy]benzoate

Participants

Reaction Steps

Methyl 3-[(2S)-1-methoxypropan-2-yl]oxy-5-phenylmethoxy-benzoate (CAS no. 851885-42-2) (50.0 g, 0.152 mmol) was dissolved in a mixture of THF:ethanol (600 mL) and the flask evacuated and purged with nitrogen (3 times). 10% Palladium on carbon (5.0 g) was added and the flask further evacuated and finally purged with hydrogen gas. The reaction mixture was stirred at ambient temperature for 20 hours until completion. The reaction mixture was evacuated and purged with nitrogen (3 times). The catalyst was filtered off, and the filtrate concentrated in vacuo to give the desired compound (36.7 g).
