Sodium hydride → (S)-tert-butyl 3-((8-chloro-3-cyanoisoquinolin-1-yl)oxy)pyrrolidine-1-carboxylate

Participants

Reaction Steps

To a solution of (S)-tert-butyl 3-hydroxypyrrolidine-1-carboxylate (126 mg, 0.674 mmol) in THF (5 mL) was added NaH (26.8 mg, 0.677 mmol) at 0° C. The mixture was stirred for 30 minutes. Next, 1,8-dichloroisoquinoline-3-carbonitrile was added and the reaction mixture was warmed to RT for 4 hours. The reaction was quenched with H2O (2 mL) and the mixture was extracted with EtOAc (3×10 mL). The organic layers were combined and concentrated in vacuo. The crude product was purified by preparative TLC to give the title compound (120 mg, 73.2%).
