Participants

Reaction Steps

Potassium hydroxide (0.52 g, 9.0 mmol) in water (2 mL) was added to a solution of 4-(4-ethoxycarbonyl-thiophen-2-yl)-piperidine-1-carboxylic acid benzyl ester (3.0 mmol) in IMS (6 mL). The reaction was stirred for 1 hour then partitioned between diethyl ether and water. The aqueous layer was acidified to pH 7 and further extracted with diethyl ether. The organic solution was dried over magnesium sulphate, filtered and the solvent removed to give the title compound (0.92 g). LCMS m/z 346 [M+H]+ RT=3.43 min (Analytical Method 4).
