Reaction Steps

But starting with 0.107 g of a mixture of 6,6-diphenyl-3-thiophen-3-yl-1-(2-trimethylsilanylethoxymethyl)-6,7-dihydro-1H-indazole and 6,6-diphenyl-3-thiophen-3-yl-2-(2-trimethylsilanylethoxymethyl)-6,7-dihydro-1H-indazole, 2.2 cm3 of ethanol and 2.2 cm3 of a 2N ethanolic solution of hydrogen chloride. After flash chromatography on a column of silica [eluent: dichloromethane], 0.024 g of 6,6-diphenyl-3-thiophen-3-yl-6,7-dihydro-1H-indazole is thus obtained in the form of a solid, the characteristics of which are as follows:
