실험 절차

To trifluoromethanesulfonic acid 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-yl ester 43 (25.0 g) obtained in Step 6 and 3′-aminoacetanilide 57 (7.33 g) were added N,N-dimethylacetamide (50.0 ml) and 2,6-lutidine (5.68 ml), and the mixture was stirred at 130° C. for 5 hrs. After allowing to cool to room temperature, methanol-water [1:2 (volume ratio), 150 ml] was added with stirring. The crystals were collected by filtration and dried to give 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 (24.8 g, yield 99%) as colorless crystals.
