実験手順

To a solution of 171 mg of 2-methyl-1-[(S)-1-(tetrahydro-furan-2-yl)methyl]-5-(2-trifluoromethoxy-phenyl)-1H-pyrrole-3-carboxylic acid methyl ester in dioxane (4 ml) and water (4 ml) was added 1.3 ml of a 1N solution of sodium hydroxide. The reaction mixture was heated at reflux for 20 hours. After such time the reaction mixture was allowed to cool down to room temperature. The mixture was diluted with diethyl ether and extracted with 1N sodium hydroxide solution. Water phases were pooled, acidified with 2N solution of hydrochloride acid and extracted twice with diethyl ether. The organic phases were pooled, washed with brine and dried with MgSO4. Solvent was removed to give 154 mg of the title compound as brownish oil; MS (ISP) 368.0 (M−H).
