2-Ethyl-1-butene → HCID 58432618, compound

Participants

Reaction Steps

Chloramine-T (10 g, 43.9 mmol) was suspended in acetonitrile (146 mL) at room temperature under nitrogen. To this suspension was added 2-ethylbut-1-ene (5.55 g, 65.9 mmol) followed by phenyltrimethylammonium tribromide (1.65 g, 4.39 mmol) in two roughly equal portions. After three days the reaction mixture was concentrated to half volume and then filtered through a sintered glass funnel. The filtrate was concentrated to half volume again which caused further precipitation. This mixture was filtered and the filtrate was partitioned between ethyl acetate and water. The organic phase was dried with MgSO4, filtered and concentrated. The crude material was purified by column chromatography using a Biotage 65i column eluting with (0-100% EtOAc/hexane) to give 2,2-diethyl-1-[(4-methylphenyl)sulfonyl]-aziridine as a colorless solid (4.5 g).
