Reaction Steps

A solution of 2 N aq. sodium hydroxide (2.5 mL) was added to a solution of N-(4-chlorobenzyl)-2-(chloromethyl)-7-methyl-4-oxo-4,7-dihydrofuro[2,3-b]-pyridine-5-carboxamide (Example 2, 1.83 g) in DMF (40 mL). The mixture was heated and a sat. aq. sodium bicarbonate solution (10 mL) was added. The reaction mixture was allowed to cool to room temperature, was poured into water, and extracted with EtOAc (3×100 mL). The combined organic layers were concentrated. The crude product was purified by column chromatography (CH2Cl2/methanol, 100/1; 50/1; 20/1; 15/1) to afford 0.258 g of the title compound as a yellow solid. Physical characteristics. M.p. 229-230° C.; 1H NMR (300 MHz, DMSO-d6) δ 10.63, 8.56, 7.42-7.32, 6.85, 5.53, 4.54, 4.51, 3.94; MS (EI) m/z 346 (M+).
