Procedure

A mixture of potassium phthalimide (1.16 g, 6.29 mmoles) and 40 ml of dried N,N-dimethylformamide was heated up to 110° C. To this mixture was added dropwise a solution of methyl 22-tosyloxydocosanoate (2.20 g, 4.19 mmoles) in 70 ml of N,N-dimethylformamide, and the reaction mixture was reacted for 2 hours at 110° C. After the completion of reaction, the reaction mixture was subjected to the same after-treatment steps as in Reference Example 2, to give methyl 22-phthalimidodocosanoate (1.57 g, 95%) having the following properties.
