Reaction Steps

A mixture of Intermediate 24b (394 mg, 2.30 mmol), (S)-3-hydroxypiperidine hydrochloride (1.00 g, 7.27 mmol) and DIPEA (1.27 mL, 7.30 mmol) in DMA (8 mL) was heated in the microwave at 170-180° C. for 9.5 h. The cooled mixture was concentrated in vacuo and applied to an SCX-2 cartridge (70 g), washing with methanol then eluting basic components with 0.4-2 M ammonia in methanol. Product containing fractions were combined and concentrated in vacuo. The residue was purified by FCC, using 0-20% MeOH in DCM, to give the title compound as a pale brown solid (204 mg, 38%). LCMS (Method 3): Rt 2.02 min, m/z 237 [MH+].
