실험 절차
A mixture of 0.113 g (0.29 mmol) of 6-(2,6-dichlorophenyl)-2-methanesulfonyl-8-methyl-8H-pyrido[2,3-d]pyrimidin-7-one of Example 39 and 0.50 g (4.10 mmol) of 4-methoxyaniline was heated, with stirring, in a 180° C. oil bath. The resulting solution was heated for 10 minutes. Much of the excess aniline was evaporated at reduced pressure. The remainder was dissolved in 2 mL of ethyl acetate. The crystals that separated from the dark solution were filtered and washed with 2 mL of ethyl acetate, wt 0.102 g.
