Procedure

27.6 ml of phosphorus oxychloride was added in drops to a solution of 27.6 g of 4 in 275 ml of pyridine at a temperature of 0-5° C., and it was stirred for another 1.5 hours at this temperature. Then, the mixture was moved into a dropping funnel and added in drops to an ice-cooled, saturated sodium bicarbonate solution. Then, it was extracted with dichloromethane, the collected organic phases were washed with brine, dried on magnesium sulfate, and the solvent was removed in a vacuum. In this way, 23.5 g (89%) of almost colorless, foamy 5 was obtained, which was used without further purification in the next stage.
