Participants

Reaction Steps

To compound 8 (as per Example H above) (80 mg, 0.25 mmol) in dry DMF (12 mL) was added 4-fluoropiperidine hydrochloride (70 mg, 0.5 mmol) and NaOAc (41 mg, 0.5 mmol) under Ar(g). After 20 minutes NaBH(OAc)3 (106 mg, 0.5 mmol) and NaBH3CN (16 mg, 0.25 mmol) were added and the suspension was stirred for 16 h. The DMF was then removed in vacuo, EtOAc (45 mL) was added along with 50% saturated brine (7 mL), the layers separated, extracted with EtOAc (2×15 mL), dried (MgSO4) and concentrated in vacuo. Purification by flash column chromatography on silica (eluant 1-2% MeOH/CH2Cl2) furnished 9 (58 mg, 0.014 mmol, 57%) as a white solid.
