Procedure
To a stirred solution of 2-({3-[(4-cyclobutyl-1,4-diazepan-1-yl)carbonyl]azetidin-1-yl}carbonyl)-1H-benzimidazole (170 mg, 0.45 mmol) in THF (10 ml) was added NaOH (1.12 ml of a 2.5 M aqueous solution, 2.8 mmol). After 5 minutes, dimethylsulfate (0.2 ml, 2.1 mmol) was added and the reaction was stirred at room temperature for 16 hours. The reaction was then concentrated at reduced pressure and purified directly via FCC (using a gradient of eluents; 98:2 to 95:5 DCM:2M NH3 in MeOH) to give the title compound (45 mg, 25% yield) as yellow oil.
