Reaction Conditions

Reaction Steps

A suspension of sodium hydride (60% dispersion in oil, 56 mg, 1.39 mmol) in dry DMF (2.0 mL) under nitrogen was treated with Intermediate 1 (46 mg, 0.28 mmol) and the mixture was stirred for 20 min. Intermediate 13d (110 mg, 0.28 mmol) was added and the mixture was heated to 60° C. for 1.75 h then quenched with MeOH. The mixture was further diluted with MeOH and applied to a pre-conditioned (MeOH) SCX-2 cartridge (10g). The cartridge was eluted with MeOH then 2M NH3 in MeOH. The relevant fractions were combined and concentrated in vacuo. The residue was dissolved in DCM containing a few drops of MeOH and purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, to give the title compound (28 mg, 19%). LCMS (Method 3): Rt 2.08 min, m/z 537, 539 [MH+].
