Procedure
Ethyl 5-methylbenzofuran-2-carboxylate, (1.19 g, 5.83 mmol) was suspended in 20 ml of 7M NH3 in MeOH. The mixture was stirred at 50° C. in a sealed tube overnight. After cooling to room temperature, the solvent was evaporated under reduced pressure to give pure 5-methylbenzofuran-2-carboxamide, as a white solid (1.02 g). LCMS retention time=1.00 minutes (LC method 3); MS (m+1)=175.8. 1H NMR (400 MHz, DMSO-d6) δ 2.40 (s, 3H), 7.45 (d, J=0.9 Hz, 1H), 7.51 (d, J=8.4 Hz, 1H), 7.53 (t, J=0.7 Hz, 1H), 7.63 (br. s., 1H), 8.05 (br. s., 1H).
