Procedure

To a stirred solution of 4-methoxycyclohexane carboxylic acid (20 mg, 0.13 mmol) in DMF/DCM (1:1) (2 ml) was added HOBt (38 mg, 0.28 mmol) and HBTU (96 mg, 0.25 mmol) and the reaction mixture stirred for 15 mins at RT. 1-(Azetidin-3-ylcarbonyl)-4-cyclobutyl-1,4-diazepane (30 mg, 0.13 mmol) in DCM (1 ml) was added and the reaction mixture stirred at RT for 16 hrs. Upon completion, the reaction mixture was evaporated at reduced pressure and purified by silica gel FCC (using DCM/MeOH/NH3; 95:5:0.5 to 90:10:1 as eluent) to give the title compound as colourless oil and as a 1:1 mixture of diastereoisomers by 1H NMR spectroscopy (5.2 mg, 11% yield).
