alpha-Benzamido(2,3-dihydro-5-benzofuranyl)acetic acid → 2-Amino-2-(2,3-dihydro-1-benzofuran-5-yl)acetic acid

Participants

Reaction Steps

The α-benzamido(2,3-dihydro-5-benzofuranyl)acetic acid (100 mg) is dissolved in 20 ml of methanol and 40 ml of water. Then 20 mg of a palladium on carbon catalyst is added and the mixture subjected to hydrogen pressure of 10 to 40 pounds/in2 for 4 hours. The mixture is filtered to remove the solid and the methanol is evaporated to give the title compound in about 60% yield. NMR(DMSO-D6)ppm(δ)7.95(s,1);6.7(m,3); 4.8(s,1);4.42(t,2);2.95(t,2).
