To a solution of [2-Cyclopropyl-1-methyl-1-(5-methyl-[1,2,4]oxadiazol-3-yl)-ethyl]-carbamic acid benzyl ester (Example 66d, 540 mg, 1.71 mmol) in ethanol (10 ml) under argon atmosphere was added palladium on charcoal 10% (54.7 mg, 514 μmol). The reaction was stirred at room temperature under a pressure of 2.5 bar hydrogen for 2 hours. The reaction mixture was filtered through a pad celite and the filter cake was washed two times with ethanol. The filtrate was evaporated down to dryness to yield the title compound (163 mg, 53%) as crude yellow oil which was used with any purification. MS (ESI, m/z): 182.2 (M+H+).
