Procedure
To a solution of benzyl 4-[(3-hydroxyazetidin-1-yl)carbonyl]azepane-1-carboxylate (97 mg, 0.29 mmol) and 4-chloro-2-methylpyridine (52 μl, 0.46 mmol) in DMSO (2 ml) was added NaH (37 mg of a 60% dispersion in mineral oil, 0.93 mmol). The mixture was stirred at room temperature for 12 hours, 50° C. for 3 hours and a further 12 hours at room temperature. The reaction was then diluted with EtOAc (20 ml) and washed with water (3×10 ml), dried (MgSO4), filtered and concentrated. The residue was purified by silica FCC (using a gradient of eluents; 99:1:1 to 95:5:1 DCM/MeOH/2M NH3 in MeOH) to give the title product as colourless oil (35 mg, 29%).
