Lithium Hydroxide → 2-(4-Benzyloxy-phenyl)-propionic acid

Participants

Reaction Steps

To a solution of methyl (R/S)-α-methyl-4-benzyloxyphenylacetate 45a (2.7 g, 10 mmol) in MeOH (25 mL) was added 1 N LiOH (15 mL). The mixture was stirred for 2 hour and concentrated. EtOAc was added followed by 1 N HCl (10 mL). The organic layer was separated and washed with brine, dried (MgSO4), and concentrated to afford the carboxylic acid (2.3 g, 90%) as a solid. MS (CI—NH3): (M+H+NH3)+=274.
