(2R)-2-hydroxypropanamide → HCID 86717556, compound

Participants

Reaction Steps

A mixture of (2R)-2-hydroxypropanamide (17.1 mg, 0.192 mmol) and triethyloxonium tetrafluoroborate (34.2 mg, 0.180 mmol) in tetrahydrofuran (0.36 mL) was stirred at room temperature for 75 min and then concentrated. The residue was dissolved in ethanol (0.14 mL), and this solution was then added to a solution of benzyl [(1R,2R,5S)-5-[(6-aminothieno[3,2-b]pyridin-7-yl)amino]-2-(cyanomethyl)cyclohexyl]carbamate (26 mg, 0.060 mmol) in ethanol (0.36 mL) in a vial. The resulting mixture was stirred at 80° C. overnight. After cooling, the mixture was concentrated and purified on silica gel, eluted with 0-10% MeOH in dichloromethane to give 18 mg of the desired product. LCMS calculated for C26H28N5O3S (M+H)+: m/z=490.2. Found: 490.0.
