Pyridine → Oleyloxyethyl phosphorylcholine

Participants

Reaction Steps

In benzene were dissolved 4.0 g of 2-[(Z)-9-octadecen-1-yl)oxyethanol and 4.6 g of 2-bromoethyl phosphorodichloridate, and following dropwise addition of 1.5 g of pyridine under ice-cooling, the mixture was stirred at room temperature. The reaction mixture was treated by the procedure of Production Example 1 including hydrolysis, quaternization, purification by silica gel column chromatography and recrystallization from chloroform-acetone to give 0.52 g (9%) of the desired product.
