Reaction Steps
To a solution of 3-aminomethyl-thiophene-2-carboxylic acid methyl ester (0.82 g, 4.79 mmol) in 1:1 MeOH-EtOH (125 mL), is added K2CO3 (0.66 g, 4.79 mmol) and the mixture is stirred at 90° C. for 5 hours. The solvent is removed in vacuo and the residue purified by silica gel column chromatography eluting with 97:3 DCM:MeOH. The title compound is isolated (0.365 g, 55%).
