Participants

Reaction Steps

To the residue of the product from step 1 (0.25 mmol) is added methanol (350 μL), hydrazine (33 μL), and Raney-Nickel (10 mg). The reaction mixture is shaken at room temperature for 16 hours, then filtered and the solution concentrated to yield ethanesulfonic acid 4-amino-benzylamide, which is used as such for the subsequent reaction.
