A mixture of methyl 3-oxo-5-(1,3-thiazole-2-yl)-4-pentenoate (132.0 g) and palladium hydroxide, 20 wt % on carbon (13 g) in MeOH (2600 ml) was stirred under hydrogen atmosphere by balloon for 4 hours. Catalyst was removed by filtration and the filtrate evaporated to give 130.0 g of methyl 3-oxo-5-(1,3-thiazole-2-yl)pentanoate as a brown liquid.
