Procedure

A solution of (3R)-3-[3-(aminomethyl)-1,2,4-oxadiazol-5-yl]-6-cyclohexylhexanoic acid (preparation 163) (177 mg, 0.53 mmol) and Et3N (186 μl, 1.33 mmol) in dioxan (500 μl) and H2O (500 μl) was treated with Boc-ON (145 mg, 0.58 mmol) and stirred at room temperature for 18 hours. The reaction mixture was diluted with H2O and extracted with EtOAc (×2). The organic extracts were combined and the solvent removed under reduced pressure. The crude material was purified on a silica column eluting with DCM:MeOH (100:0) gradually changing to (90:10) to afford the title compound as a colourless gum (15 mg, 55%).
