Hydrazine, 1-(1,1-dimethylethyl)-1-phenyl-

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred suspension of zinc dust (5.14 g, 0.079 mol) in water (15 ml) was added dropwise a solution of the compound of Example 560B (3.5 g, 0.02 mol) in acetic acid (9 ml) and the resultant mixture was stirred for 1 hr at r.t. Dichloromethane (20 ml) was added, the mixture was adjusted to pH 8–9 with 15% NaOH, The zinc dust was removed by filtration, and the crude reaction mixture was extracted with dichloromethane. The combined organic layers were dried (MgSO4). Yield 1.97 g (60%). The zinc dust was removed by filtration the crude reaction mixture was extracted with dichloromethane The combined organic layers were dried (MgSO4)
