A procedure similar to that described in Preparation 59 was repeated, except that 7.4 g of 2-t-butyldimethylsilyloxymethyl-1H-imidazo[4,5-c]pyridine (prepared as described in Preparation 71), 1.23 g of sodium hydride (as a 55% by weight dispersion. in mineral oil), 2.0 ml of methyl iodide and 200 ml of dimethylformamide were used, to give the title compound as a crude product. This crude product was purified by column chromatography through silica gel, using a 10:1 by volume mixture of ethyl acetate and methanol as the eluent, to give 3.30 g of the title compound, melting at 93°-95° C.
