実験手順: The title compound was prepared from [4-carbamoyl-3-(2,3,6-trifluoro-4-methyl-benzyloxy)-isothiazol-5-yl]-carbamic acid phenyl ester and 4-(4-methyl-piperazin-1-yl)-butylamine by the procedure analogous to Example 1. MS (APCl, m/z): 515 [M+H]+.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Following the procedure of Example 20, 2.0 g of 2,7-diamino-6-(2,6-dichlorophenyl)-pyrido[2,3-d]-pyrimidine from Example 1 was reacted with 15 mL of 1-(4-aminobutyl)-4-methyl-piperazine to give the title compound.

実験手順: Following the procedure of Example 20, 2.0 g of 2,7-diamino-6-(2,6-dichlorophenyl)-pyrido[2,3-d]pyrimidine from Example 1 was reacted with 15 mL of 1-(4-aminobutyl)-4-methyl-piperazine to give the title compound.

反応条件: temp:170.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of 0.152 g (0.43 mmol) of 6-(2,6-dichlorophenyl)-8-methyl-2-methylsulfanyl-8-pyrido[2,3-d]pyrimidin-7-one of Example 37 and 0.50 g (2.90 mmol) of 1-(4-aminobutyl)-4-methylpiperazine was heated with stirring in a 170° C. oil bath. After 2 minutes, solution was complete. After 2 hours, the solution was cooled to room temperature, and the dark gum was dissolved in 25 mL of ether. The solution was washed with 4×5 mL of water. Most of the color went into the water wash. The ether solution was dried over potassium carbonate, filtered, and concentrated to ca. 2 mL volume. The crystals that separated on inducement were filtered and washed with ether; wt 0.063 g; mp 130°-132° C.; was heated After 2 hours the solution was cooled to room temperature The solution was washed with 4×5 mL of water wash The ether solution was dried over potassium carbonate filtered concentrated to ca. 2 mL volume The crystals that separated on inducement were filtered washed with ether
