Procedure

490 mg of 5-(4,6-dimethoxy-2-pyrimidinyl)-furo[3,4-b]pyridine-7(5H)-one is dissolved in 50 ml of methanol and the mixture heated with stirring at 50° C. until a homogeneous solution is formed (ca 1/2 hr). 2.6 g of NaOCl is added dropwise and the solution heated for a further 1/2 hr at 55° C. 0.208 g of 50% NaOH is added at 55° and the mixture heated for a further 1/2 hr at this temperature and then cooled in an ice-bath and acidified with 1 ml conc. HCl. The solvent is evaporated and the residue partitioned between 50 ml of CH2Cl2 and 50 ml of water. The organic phase is concentrated to give a white solid, m.p. 71°-73°.
