Procedure

The reaction and aftertreatment were conducted in the same manner as in Example 14b by using the N-(2,4-dimethoxybenzyl)pyrimidine-4-amine (0.40 g, 1.63 mmol) prepared in Example 14a, 2,4-difluorobenzenesulfonyl chloride (0.69 g, 3.26 mmol), 1,4-diazabicyclo[2.2.2]octane (0.37 g, 3.26 mmol) and acetonitrile (11 mL), to yield the title compound (403.8 mg, 59%) as a colorless solid.
