실험 절차

4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (1.24 g) in dry DMF (30 ml) was treated with EDC (1.48 g) and HOBT (0.67 g). The reaction mixture was stirred at rt for 5 min, followed by the addition of 1-(cyclobutyl)hexahydro-1H-1,4-diazepine dihydrochloride (D4) (1.13 g) and triethylamine (2.7 ml). The mixture was stirred at rt overnight. The reaction mixture was then poured into water (250 ml) and extracted with EtOAc (2×35 ml). The combined organic layers were washed with saturated aqueous sodium hydrogen carbonate (2×30 ml) followed by water (5×30 ml). After drying (magnesium sulphate) the solution was evaporated to give the title compound (D7) as an oil (0.84 g). MS electrospray (+ve ion) 385 (MH+).
