Reaction Steps

A mixture of 5-{1-ethyl-1-[4-(2-hydroxy-3,3-dimethyl-butoxy)-3-methyl-phenyl]-propyl}-3-methyl-thiophene-2-carboxylic acid hydrazide (432 mg, 1 mmol), 1,1′-carbonyldiimidazole (405 mg, 2.5 mmol) and triethylame (0.28 ml, 2 mmol) in THF (10 ml) is stirred at reflux overnight. It is diluted with EtOAc, washed with 1N HCl solution. The organic phase is concentrated and chromatographed (Hex to 20% EtOAc/Hex to give the title compound (290 mg, 63%).
