Procedure

A procedure similar to that described in Preparation 2 was repeated, except that 780 mg of methyl indolin-1-ylacetate (prepared as described in Preparation 8), 200 mg of lithium aluminum hydride and 12 ml of anhydrous tetrahydrofuran were used, to give 580 mg of the title compound having Rf=0.31 (on silica gel thin layer chromatography using a 2:1 by volume mixture of hexane and ethyl acetate as the developing solvent)
