Procedure
A mixture of (2S,3R)-allyl 2-(aminomethyl)-3-methylpiperidine-1-carboxylate (0.804 g, 3.787 mmol), 2,5-dichlorobenzo[d]oxazole (0.712 g, 3.787 mmol) and DIPEA (1 mL, 5.68 mmol) in acetonitrile (15 mL) was heated at 40° C. overnight. The solvent was removed in vacuo and the crude was purified via silica gel with 0˜100% EtOAc/hexanes to obtain the title compound. ESI-MS (m/z): 364 [M+1]+.
