Participants

Reaction Steps

3-Bromomethyl-thiophene-2-carboxylic acid methyl ester (1.297 g, 5.54 mmol) is dissolved in DMF (30 mL) and MeOH/NH3 is added (30 mL). The reaction mixture is stirred at room temperature for 1 hour, and concentrated in vacuo. Purification of the residue by silica gel column chromatography eluting with 95:5 and 93:7 DCM:MeOH affords the title compound (0.82 g, 86%).
