Yield:-
Reaction Conditions:
in ethanol at 70;
Steps:
12.B
Part B: Compound 707 (478 mg, 2.14 mmol) was dissolved in ethanol (6 mL) and methylhydrazine (0.5 mL) and stirred at 70 0C overnight. The reaction was quenched with water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate/hexanes to provide compound 708 (200 mg). HPLC-MS tR = 1.5 min (UV2S4 nm); mass calculated for formula C10H10BrN3 253.0, observed LCMS m/z 254.1 (M+H).
