실험 절차

1-(Cyclobutyl)-hexahydro-1H-1,4-diazepine dihydrochloride (D4) (0.15 g) was stirred with diethylaminomethyl polystyrene (1.0 g), HOBT (0.045 g), 4-(1,1-dioxido-4-thiomorpholinyl)benzoic acid (0.186 g) in DCM (5 ml). EDC (0.165 g) was then added and the reaction was stirred at rt for 16 h. The polymer supported base was filtered off and the filtrate was diluted with DCM (10 ml) and washed with saturated sodium hydrogen carbonate (2×15 ml). The organic layer was then loaded directly onto a silica column and eluted with 0-10% MeOH (containing 10% 0.880 ammonia solution)/DCM. The isolated free base product was dissolved in DCM (5 ml) and treated with excess 1N HCl/diethyl ether solution (1 ml) and stirred for 10 min. The mixture was evaporated (co-evaporated with acetone 2×10 ml), triturated with acetone, then dried at 50° C. under high vacuum for 16 h to yield the title compound (E9) as a pale solid (0.086 g). MS electrospray (+ion) 392 (MH+). 1H NMR δ (DMSO-d6): 10.5 (1H, s), 7.37 (2H, d, J=8.4 Hz), 7.07 (2H, d, J=8.8 Hz), 4.18-3.24 (10H, m), 3.11 (4H, m), 3.10-2.85 (2H, m), 2.45-1.98 (7H, m), 1.80-2.54 (2H, m).
