Methylamine → HCID 59278130, compound

Participants

Reaction Steps

To a stirred solution of trifluoromethanesulfonic acid 4-((S)-1-{[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-propyl)-6-methanesulfonyl-pyridin-2-yl ester (0.08 g, 0.13 mmol) in DMF (2 mL) was added a 2.0 M solution of methylamine in THF (0.150 mL, 0.30 mmol) followed by DIPEA (0.05 mL, 0.3 mmol). After 16 hours, the mixture was diluted with saturated aqueous ammonium chloride (5 mL) and extracted with ethyl acetate (3×5 mL). The combined organic layers were dried over sodium sulfate and concentrated onto silica gel. The crude material was purified by silica gel chromatography eluting with a gradient of 0-100% ethyl acetate in hexanes to afford the title compound.
