After washed with water and dried over Na2SO4, the solvent was evaporated and the residue was used in the next step without purification. The resulting bromoacetamide and N,N'-ditosylhydrazine (1036.0 mg, 3.04 mmol) were dissolved in THF (10.0 mL) and cooled down to 0 C, then DBU (1158.2 mg, 7.60 mmol) was added drop wise and stirred at room temperature for 1 h. After quenched with NaHCO3 aq and extracted with diethyl ether three times, the organic phase was dried over Na2SO4 and evaporated to give crude product.

The reaction was allowed to warm to ambient temperature and monitoredby GC/MS. Upon consumption of the starting amine, The reaction was diluted with5 vol CH2Cl2 and washed 3x 5vol H2O. The aqueouslayer was back extracted 3x1 vol. The combined organics were dried over Na2SO4.The crude material was concentrated and subjected to the next reaction. Whennecessary, purification via flash chromatography was employed Toa chilled solution solution of the α-Bromoamide in acetonitrile (5 vol) wasadded 4 equiv. of benzylamine or N-benzylmethylamine.
