실험 절차

To a stirred solution of 3-[(4-cyclobutyl-1,4-diazepan-1-yl)carbonyl]-N-(cyclohexylmethyl)azetidine-1-carboxamide (26 mg, 0.069 mmol) in dry DMF (1 ml) at 0° C. under a nitrogen atmosphere was added sodium hydride (4.1 mg of a 60% dispersion in mineral oil, 0.103 mmol). The resulting suspension was stirred at 0° C. for 30 min. Methyl iodide (4.3 μl, 0.069 mmol) was added and the reaction mixture allowed to warm to RT and was stirred for 16 hrs. The reaction mixture was poured onto ice-water, extracted with EtOAc (3×5 ml), the combined organics washed with brine (5 ml), dried (MgSO4), filtered and concentrated at reduced pressure. Purification by preparative HPLC provided the title compound (5.6 mg, 21% yield) as colourless oil.
