2-(N-benzyloxycarbonyl-L-valyl)amino-6methylbenzoic acid → 6-methyl-2-(L-valylamino)benzoic acid

Participants

Reaction Steps

2-(N-benzyloxycarbonyl-L-valyl)amino-6methylbenzoic acid (1.21 g) was dissolved in a mixture of methanol (99 ml) and water (1 ml), and 10% Pd-C (200 mg) was added to the solution. The mixture was stirred under a hydrogen atmosphere at room temperature for three hours. After Pd-C was removed by Hyflo-Super-Cel, the filtrate was concentrated to obtain 830 mg of 6-methyl-2-(L-valylamino)benzoic acid.
