Reaction Steps
To a solution of Intermediate 85g (1.08 g, 3.58 mmol), (5-fluoro-pyridin-2-yl)-hydrazine (500 mg, 3.93 mmol) and DIPEA (1.38 g, 10.7 mmol) in DCM (120 mL) was added HATU (2.04 g, 5.37 mmol) and the mixture stirred at RT for 2 h. The solution was washed with 10% aq. K2CO3 solution, brine, dried (MgSO4), and concentrated in vacuo. The residue was purified by FCC, using 0-6% [2M NH3 in MeOH] in DCM, to give the title compound as a pale yellow oil (1.37 g, 90%). LCMS (Method 4): Rt 2.74 min, m/z 425 [MH+].
