Procedure

To a stirred solution of (4-fluorophenyl)methanol (27 mg, 0.2 mmol) in DMSO (1.5 mL) was added NaH (8.5 mg, 0.2 mmol, 60% purity) at RT. The mixture was stirred for 1 h and a solution of 1 1-[(4-cyclobutyl-1,4-diazepan-1-yl)carbonyl]azetidin-3-yl methanesulfonate (33 mg, 0.1 mmol) in DMSO (0.5 mL) was added. The resulting mixture was stirred at 100° C. overnight, cooled to RT and diluted with EtOAc. The crude mixture and washed with water/brine; 1/1 solution, dried (Na2SO4), filtered and concentrated at reduced pressure. Purification by preparative HPLC provided the title compound as colourless oil (8 mg, 18%).
