Yield: 65%
Reaction Conditions:
with hydrazine hydrate at 100 - 125; for 2 h;
Steps:
I-3.3.2 Synthesis of Intermediate 1-3.2
1-3.1 (397 mg, 1.65 mmol) and hydrazine hydrate (1 mL, 20.6 mmol) are heated to 100 °C for 1 h and at 125 °C for 1 h. To the cool reaction mixture DCM and water are added and the aqueous layer extracted twice with DCM. The combined organic layers are washed with brine, dried, concentrated and the residue purified via column chromatography (using solvent mixture cyclohexane / EA = 3:1). Yield 65%. m/z 226 [M+H]+, m/z 224 [M+H]-, rt 0.58 min, LC-MS Method b.
