Participants

Reaction Steps

To a solution of tert-butyl 7-chloro-3-(2-hydroxyethyl)-1H-pyrrolo[2,3-c]pyridine-1-carboxylate (233 mg, 0.79 mmol) in PhMe (15 mL) was added 4-trifluoromethoxyphenol (0.15 mL, 1.2 mmol), triphenylphosphine (309 mg, 1.2 mmol), and diisopropylazodicarboxylate (0.23 mL, 1.2 mmol) at r.t. After 20 min, the mixture was concentrated in vacuo, and the crude material was purified on silica (gradient elution, 0-30% EtOAc/hexanes) to yield the title product (349 mg). HRMS (ESI) calc (M+H)+=457.1136. found 457.1133.
