It is sufficient to use a large excess of the molar amount of LL-bityrosine tIljt, and dioxane, acetone, etc. are preferred as the solvent. Further, the reaction is preferably carried out at -20°C to 50°C for 30 minutes to S hours, especially at 20°C to 0°C.
°C is preferred. In addition, for mixed formyl LL-bityrosine [Illt], formic acid may be used in a proportion of about 2 to 5 moles and DCC in a proportion of about 2 moles, and the solvent is preferably pyridine, dimethylformamide, tetrahydrofuran, etc., and the reaction is carried out at 0°C. It is preferable to carry out the reaction at ˜SO° C. for 2 to 70 hours. When using formic acid-water-soluble lupodiimide as a mixed formylating agent, the solvent is preferably N-methylmorpholine, dimethylpyridine, etc., and the ratio of their use is 1 mol of LL-bityrosine ( ■) On the other hand, formic acid should be used in a proportion of about 2 to 70 moles, and water-soluble carbodiimide should be used in a proportion of about Ω to S mole. What if N-methylmorpholine is used as a solvent? This may be about 2 to 3 moles. In the method of the present invention, among the mixed formylating agents,
It is particularly preferred to use formic acid-acetic anhydride.
