실험 절차

To 70 ml (0.245 mol) of sodium bis(2-methoxyethoxy)aluminium hydride (70% solution in toluene) and 30 ml of dry toluene is added dropwise with stirring a solution of 9.4 g (0.041 mol) of N-(4-methoxy-2-methyl-thien-3-yl)-ethoxyacetamide in 125 ml of dry toluene. After the exothermic reaction has subsided, stirring is continued for a further 90 minutes and the reaction solution then cautiously added in small portions at -10° to 100 ml of 20% KOH solution.
