Tert-butyl (5-(chloromethyl)-1,3,4-oxadiazol-2-yl)carbamate (141 mg, 0.606 mmol) was added to a solution of 2-(4-(benzyloxy)phenyl)cyclopropanamine (enantiomer (−)) (145 mg, 0.606 mmol) and K2CO3 (166 mg, 1.213 mmol) in dry DMF (1.5 mL) and stirred at RT for 2 h. After completion, the reaction mixture was poured into ice water (10 mL) and extracted with EtOAc (4×10 mL). The combined organic extracts were washed with water (3×10 mL), brine (10 mL), dried over anhydrous Na2SO4, filtered and concentrated under vacuum. The residue obtained was purified by column chromatography (SiO2) using MeOH:CHCl3 (1:99) as eluent to afford tert-butyl (5-(((2-(4-(benzyloxy)phenyl)cyclopropyl)amino)methyl)-1,3,4-oxadiazol-2-yl)carbamate (enantiomer-(−)) (100 mg, 37.7%) as a pale green liquid.
