実験手順

900 mg (3.53 mmol) tert-butyl[2-(3-isopropyl-[1,2,4]oxadiazol-5-yl)-ethyl]-carbamate are placed in 10 ml dichloromethane, 20 ml 1 molar ethereal hydrochloric acid are added. The reaction mixture is stirred for 16 hours at ambient temperature. After the addition of a further 10 ml ethereal hydrochloric acid the mixture is stirred for another 72 hours at ambient temperature and 4 hours at 40° C. The suspension is evaporated down. The residue is dissolved in acetone, mixed with diethyl ether and suction filtered.
