Glycolic Acid → HCID 178519921, compound

Participants

Reaction Steps

A procedure similar to that described in Preparation 43 was repeated, except that 7.00 g of 5-bromo-2,3-diaminopyridine (prepared as described in Preparation 57) and 8.50 g of glycolicacid 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 7.05 g of the title compound, melting at 230°-233° C.
