Procedure

The mixture of 2-[4-(1-hydroxy-ethyl)-3-(2-m-tolyl-ethoxy)-benzoylamino]-indane-2-carboxylic acid methyl ester and 2-[4-(1-hydroxy-ethyl)-3-(2-m-tolyl-ethoxy)-benzoylamino]-indane-2-carboxylic acid ethyl ester obtained in example 9 (50 mg) was dissolved in DCM, and diethylaminosulfur trifluoride (33 mg, 0.204 mmol) was added in two portions (second portion after 3.5 h). After complete conversion as detected by HPLC, the mixture was partitioned between EA and a saturated aqueous sodium hydrogencarbonate solution and the aqueous phase extracted with EA. The combined organic extracts were dried over sodium sulfate, filtered and evaporated to dryness. The residue was stirred with a HEP/diethyl ether mixture, filtered, and dried in vacuo. The obtained ester was hydrolyzed in analogy to example 2 to give 12 mg of the title compound.
