Procedure
Ethyl 1-(2,4-difluorobenzyl)-5-formyl-1H-pyrrolo[2,3-c]pyridine-2-carboxyl ate. The title compound can be prepared by alkylation of ethyl 5-formyl-1H-pyrrolo[2,3-c]pyridine-2-carboxylate (prepared according to J.-F. Rousseau, R. H. Dodd, X. Doisy, P. Potier, Heterocycles 1989, 28, 1101-1113) and 2,4-difluorobenzyl bromide in a manner similar to step (a) in Example 1. (b) 1-(2,4-Difluorobenzyl)-(2-ethoxycarbonyl)-1H-pyrrolo[2,3-c]pyridine-5-carboxylic acid. The title compound can be prepared by oxidation of ethyl 1-(2,4-difluoro-benzyl)-5-formyl-1H-pyrrolo[2,3-c]pyridine-2-carboxylate according to the procedure by R. H. Dodd, M. Le Hyaric, Synthesis 1993, 295-287. (c) Ethyl 1-(2,4-Difluorobenzyl)-5-hydroxycarbamoyl-1H-pyrrolo[2,3-c]pyridine-2-carboxylate. The title compound can be prepared from 1-(2,4-difluorobenzyl)-(2-ethoxycarbonyl)-1H-pyrrolo[2,3-c]pyridine-5-carboxylic acid following in a manner similar to step (c ) in Example 1.
