Reaction Steps
A mixture of methyl benzofuran-6-carboxylate (17.8 g, 100 mmol) and 10% Pd/C (10.5 g) in MeOH was stirred under hydrogen atmosphere at 50 psi for 2 h. The catalyst was removed by filtration. The solvent was removed under reduced pressure to afford the desired methyl 2,3-dihydrobenzofuran-6-carboxylate (17.8 g, 98.5% yield). 1H NMR (400 MHz, CDCl3) δ: 7.57 (d, J=7.6, 1H), 7.40 (s, 1H), 7.23 (d, J=7.6, 1H), 4.61 (t, J=8.8, 2H), 3.89 (s, 3H), 3.25 (t, J=8.8, 2H).
