Procedure

Compound 262 (300 mg, 0.860 mmol) was dissolved in THF (5.0 mL), and 1-(2-pyrimidinyl)piperazine (0.370 mL, 2.58 mmol) was added thereto, followed by stirring at room temperature for 16 hours. Further, 1-(2-pyrimidinyl)piperazine (0.370 mL, 2.58 mmol) was added to the reaction mixture, followed by stirring at room temperature for 2 hours. Water and aqueous saturated sodium bicarbonate solution were added to the reaction mixture, and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (hexane:ethyl acetate=1:2) to afford the entitled Compound 278 (345 mg, 84%) as pale yellow crystals.
