Cyclopropanecarboxamide → HCID 86717527, compound

Participants

Reaction Steps

A mixture of cyclopropanecarboxamide (72.6 mg, 0.853 mmol) and triethyloxonium tetrafluoroborate (0.161 g, 0.845 mmol) in THF (2 mL) was stirred at room temperature for 2 h. The solvent was removed and the residue dissolved in ethanol (0.48 mL) and added to a suspension of {(2R,5S)-5-[(6-aminothieno[3,2-b]pyridin-7-yl)amino]tetrahydro-2H-pyran-2-yl}methanol (72.0 mg, 0.258 mmol) in ethanol (1.8 mL). The mixture was stirred at 80° C. for 1 h. The reaction mixture was cooled to room temperature, diluted with methanol, and purified with prep-LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product. LCMS calculated for C17H20N3O2S (M+H)+: m/z=330.1. Found: 330.0.
