Reaction Steps

To a cooled solution of tert-butyl 2-(5-methyl-1,2,4-oxadiazol-3-yl)piperidine-1-carboxylate (55 mg, 0.21 mmol; which may be prepared as described in Step 2) in dichloromethane (1.7 mL) was added dropwise HCl 4N in dioxane (1.3 mL). The solution was warmed to room temperature and stirred for 2 h. The solvent was evaporated under reduced pressure to give the title compound (47 mg, quantitative) as a white powder.
