Participants

Reaction Steps

A mixture of N-(benzyloxycarbonyl)-4-(1,3-dimethyl-2,4-dioxo-5-pyrimidinyl)-3-methyl-L-phenylalanine methyl ester (0.34 mmol, 159 mg), cyclohexene (1 mL) and 10% palladium on carbon (100 mg) in ethanol (3 mL) was heated to reflux for 20 min. Then, it was filtered through a pad of celite and the pad was washed with ethanol (10 mL). The combined filtrate was concentrated and the residue was dried under high vacuum to afford 96 mg (85% yield) of 4-(1,3-dimethyl-2,4-dioxo-5-pyrimidinyl)-3-methyl-L-phenylalanine methyl ester as a sticky yellow solid. ES-HRMS m/e calcd for C17H21N3O4 (M+Na) 354.1424, found 354.1424.
