Versuchsvorschrift

To a chloroform solution (3.0 mL) of 4-chloro-1-(4-chlorobenzyl)-1,3,5-triazin-2(1H)-one (128 mg, 0.500 mmol) synthesized in Reference Synthesis Example 11, triethylamine (70.0 μL, 0.500 mmol) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,6-tetrahydropyridine (156 mg, 0.750 mmol) were added and the resultant mixture was stirred at room temperature for 4 hours. After completion of the reaction, water was added to the reaction solution and extraction from the resultant mixture with chloroform was performed. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/0→4/1) to obtain the title compound (86.0 mg, yield 40%).
