tert-Butanol → HCID 10900116, compound

Participants

Reaction Steps

Lithium (1.73 g, 249 mmol) was added in portions to a stirred solution of benzonitrile (10.2 mL, 10.3 g, 99.9 mmol) and t-BuOH (9.6 mL, 7.4 g, 100 mmol) in NH3 (50 mL) and THF (10 mL) under N2 at −78° C. After stirring for 25 minutes, t-butyl bromoacetate (29.5 mL, 39.0 g, 200 mmol) was added dropwise. After 1 hour, ammonium chloride (41.8 g, 781 mmol) was added in portions. The reaction mixture was slowly warmed to room temperature while the NH3 was removed with a stream of N2. Water (125 mL) was added and the mixture extracted with MTBE (3×50 mL). The combined organic extracts were dried (MgSO4) and concentrated under reduced pressure. Flash chromatography (SiO2, CH2Cl2-1:14 MTBE:CH2Cl2) afforded 16.0 g (73%) of product as an oil.
