Versuchsvorschrift

To trifluoromethanesulfonic acid 1-(2-fluoro-4-iodophenyl)-3,6,8-trimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydro-pyrido[2,3-d]pyrimidin-5-yl ester 70 (3.00 g) obtained in Step 6 and N-(3-aminophenyl)methanesulfonamide 44 (1.14 g) were added N,N-dimethylacetamide (6.00 ml) and 2,6-lutidine (0.712 ml), and the mixture was stirred at 130° C. for 4 hrs. After allowing to cool to room temperature, methanol/water [1:2 (volume ratio), 18.0 ml] was added under stirring. The crystals were collected by filtration and dried to give N-{3-[1-(2-fluoro-4-iodophenyl)-3,6,8-trimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydro-pyrido[2,3-d]pyrimidin-5-ylamino]phenyl}methanesulfonamide 71 (3.13 g, yield 98%) as a pale-gray solid.
