Procedure

A procedure similar to that described in Example 6 was repeated, except that 30.8 g of methyl 4-nitro-phenoxyacetate (prepared as described in Preparation 36), 5.0 g of 10% w/w palladium-on-charcoal and 500 ml of methanol were used, to give 25.8 g of the title compound having Rf=0.79 (on silica gel thin layer chromatography using ethyl acetate as the developing solvent).
