Reaction Steps
The product prepared in step (d) above (0.05 mol) and dry pyridine (1 ml) are dissolved in dry ether (20 ml) and cooled to 0° C. Phosphorous tribromide (0.025 mol) in 20 ml dry ether is added dropwise with stirring. The reaction mixture is then refluxed for 3 hours. After cooling the mixture to 0°, the excess PBr3 is destroyed by adding crushed ice. The ether layer is washed and dried. The ether is removed and the title product is obtained by distillation.
