Reaction Steps

2 g of 17-bromoheptadecanoic acid are added to 2.14 g of potassium phthalimide in 40 cm3 of N,N-dimethylformamide and the mixture is heated for 6 hours at a temperature in the region of 80° C. The solution is cooled to about 20° C., it is poured into 100 cm3 of distilled water and 10 cm3 of 2N hydrochloric acid are added dropwise. The solid formed is separated by filtration. 5.13 g are obtained of a residue which is chromatographed on a column with a diameter of 4 cm containing 250 g of silica (0.020-0.045 mm) eluted with a 95/5 (by volume) mixture of methylene chloride and methanol. The first 4 fractions are discarded, the following 3 are combined and concentrated to dryness under reduced pressure (2.7 kPa) at a temperature in the region of 40° C. 3.39 g of 17-phthalimidoheptadecanoic acid are thus obtained in the form of a white solid.
