Cyclopropanecarboxamide → HCID 178511078, compound

Participants

Reaction Steps

A mixture of cyclopropanecarboxamide (65.0 mg, 0.764 mmol) and triethyloxonium tetrafluoroborate (145 mg, 0.763 mmol) in tetrahydrofuran (0.4 mL) was stirred at room temperature for 1 h and then concentrated. A mixture of {trans-4-[(6-aminothieno[3,2-b]pyridin-7-yl)amino]cyclohexyl}acetonitrile (22 mg, 0.077 mmol), and the above made reagent in ethanol (0.70 mL) was heated at reflux for 2 h. The mixture was purified on prep-HPLC (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 (2.5 mg, 9.7%). LCMS calculated for C19H21N4S (M+H)+: m/z=337.1. Found: 337.0.
