실험 절차

A procedure similar to that described in Preparation 43 was repeated, except that 1.90 g of 3-amino-6-isopropoxy-2-methylaminopyridine (prepared as described in Preparation 101), and 2.39 g of glycolic acid were used, and that the product was purified by column chromatography through silica gel, using a 10:1 by volume mixture of ethyl acetate and methanol, to give 0.58 g of the title compound, melting at 125-127° C.
