Versuchsvorschrift

A procedure similar to that described in Preparation 2 was repeated, except that 8.0 g of methyl 1-methyl-indoline-2-carboxylate (prepared as described in Preparation 5), 1.91 g of lithium aluminum hydride and 250 ml of tetrahydrofuran were used, to give 6.85 g of the title compound having Rf=0.35 (on silica gel thin layer chromatography using a 2:1 by volume mixture of hexane and ethyl acetate as the developing solvent).
