2-(7-methyl-1H-indazol-5-ylmethylene)-succinic acid 1-methyl ester → 4-methoxy-3-((7-methyl-1H-indazol-5-yl)methyl)-4-oxobutanoic acid

Participants

Reaction Steps

A suspension of 2-(7-methyl-1H-indazol-5-ylmethylene)-succinic acid 1-methyl ester (0.4440 g, 1.62 mmol) and 10% Pd/C (0.04 g) in ethyl acetate (15 mL) and methanol (5 mL) was hydrogenated in a Parr apparatus overnight at 50 psi. The reaction mixture was filtered through a pad of celite and the filtrate evaporated to give the desired product as a yellow solid (100%). Mass spec.: 277 (MH)+.
