Benzene → HCID 54075037, compound

Participants

Reaction Steps

To a mixture of 2.3 g (0.007 mol) of (--)-3-phenoxy-N-methylmorphinan, 150 ml of benzene and 0.35 g of potassium carbonate was added dropwise, 3.3 g of 2,2,2-trichloroethyl chloroformate. The reaction mixture was stirred at reflux for 6 days. The mixture was diluted with ether and extracted with 4 N hydrochloride acid. The organic phase was washed with dilute ammonium hydroxide, water, and dried. Removal of solvent gave 3.4 g (99%) of the product (--)-3-phenoxy-N-trichlorocarbethoxymorphinan. For analysis, a sample of this compound was distilled, bp 230°-240°/0.05 mmHg, [α]25D-119.65° (c 0.95, MeOH).
