실험 절차

A mixture of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (100 mg, 0.4 mmol), 4-(2-aminoethyl)pyridin-2(1H)-one hydrobromide (96 mg, 0.44 mmol), HATU (182 mg, 0.48 mmol) and DIEA (155 mg, 1.20 mmol) in 30 mL of DCM was stirred at room temperature overnight. The solution was washed with sat NaHCO3 (2×30 mL), brine (30 mL), dried over anhydrous sodium sulfate, concentrated under reduce pressure to give crude N-(2-(2-oxo-1,2-dihydropyridin-4-yl)ethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (160 mg) and used without further purification. LC-MS: 369 [M+H]+, tR=1.35 min.
