Hydrochloric Acid → 1-cyclobutyl-4-{[1-(tetrahydro-2H-pyran-4-ylacetyl)azetidin-3-yl]carbonyl}-1,4-diazepane

Participants

Reaction Steps

To a stirred solution of 1-(azetidin-3-ylcarbonyl)-4-cyclobutyl-1,4-diazepane (30 mg, 0.13 mmol) and DIPEA (42 μl, 0.25 mmol) in DCM (1 ml) was added tetrahydropyran-4-yl acetyl chloride (21 mg, 0.13 mmol) in DCM (1 ml). The reaction mixture stirred at RT for 16 hrs. Upon completion, water and 1M HCl were added and the reaction mixture was washed with DCM (3×5 ml). The combined organic phases were dried (MgSO4), filtered and concentrated at reduced pressure. The residue was purified by preparative HPLC to afford the title compound as colourless oil (1.2 mg, 3% yield).
