Procedure
A procedure similar to that described in Preparation 43 was repeated, except that 2.62. g of 3-amino-2-methylamino-6-phenylthiopyridine (prepared as described in Preparation 89) and 2.58 g of glycolic acid were used, and that the product was purified by column chromatography through silica gel, using a gradient elution method, with mixtures of ethyl acetate and methanol in ratios ranging from 50:1 to 10:1 by volume as the eluent, to give 1.80 g of the title compound, melting at 119-120° C.
