Participants

Reaction Steps

A mixture of 2 (3.13 g, 1 mmol) in CH3COOH (15 ml) was cooled to −5° in iced bath. A mixture KSCN (6.36 g, 4.04 mmol) in CH3COOH (15 ml) added to the flask that contained 4 and CH3COOH at −5° in iced bath. A solution of bromine (0.80 ml) in CH3COOH (10 ml) is added dropwise to a stirred mixture of 4, KSCN and CH3COOH at −5° in iced bath. The reaction mixture is stirred for 1 h at room temperature. The mixture is extracted with ethyl acetate. The extracts are washed with water, brine, dried over magnesium sulfate, filtered and concentrated in vacuo.
