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 (30.0 g) obtained in the same manner in Example 4-2, Step 6 to be mentioned later and N-(3-aminophenyl)methanesulfonamide 44 (10.9 g) were added N,N-dimethylacetamide (60.0 ml) and 2,6-lutidine (6.82 ml), and the mixture was stirred at 130° C. for 3.5 hrs. After allowing to cool to room temperature, methanol (60 ml) was added with stirring and the mixture was stirred for 2 hrs. The crystals were collected by filtration and dried is 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}methanesulfonamide 45 (30.5 g, yield 96%) as colorless crystals.
