Reaction Steps

1-[(2-chlorophenyl)carbonyl]-5-(ethyloxy)-1,2,3,6-tetrahydropyrazine (I39) (0.755 g, 2.83 mmol) dissolved in Dichloromethane (DCM) (10 mL) was added to hydrazine hydrate (0.220 mL, 7.08 mmol, commercially available from e.g. Alfa Aesar, Acros or Fluka) dissolved in Dichloromethane (DCM) (5 mL) and stirred at 25° C. for 4 hr. The solvents were removed in vacuo and the residue azeotroped with toluene (3×25 mL), to afford product in 715 mg that was used in the subsequent step without further purification.
