Procedure
Under a nitrogen atmosphere, to a solution (1.57 g) of 28% sodium methoxide in methanol was added tetrahydrofuran (40 ml), N-{3-[3-cyclopropyl-1-(2-fluoro-4-iodophenyl)-6,8-dimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydro-pyrido[2,3-d]pyrimidin-5-ylamino]phenyl}acetamide 58 (5.00 g) obtained in Step 7 was added, and the mixture was stirred at room temperature for 4 hrs. Acetic acid (0.56 ml) was added, and the mixture was stirred at room temperature for 30 min. Water (40 ml) was added and the mixture was further stirred for 1 hr. The crystals were collected by filtration and dried to give N-{3-[3-cyclopropyl-5-(2-fluoro-4-iodophenylamino)-6,8-dimethyl-2,4,7-trioxo-3,4,6,7-tetrahydro-2H-pyrido[4,3-d]pyrimidin-1-yl]phenyl}acetamide 59 (4.75 g, yield 95%) as colorless crystals.
