で得られた。[Formula] R 6 -N=C=O () [In the formula, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 represent the above]. This reaction takes place at temperatures between 70 and 120°C.
Advantageously, it is carried out in a suitable solvent such as dioxane, benzene, toluene, cyclohexane, etc. over a period of 24 to 72 hours. At the end of the reaction, the products can be isolated and purified by customary methods such as chromatography and/or crystallization and salt formation. The starting materials used in this process according to the invention are known compounds or can be prepared in conventional manner starting from known compounds; furthermore, some compounds of the formula are described in JP-A-58-24584 and Belgium It is described in Patent No. 888243. Some compounds with the general formula and their production methods are:
JP-A-56-156279 and the corresponding Belgian Patent No. 888243 and West German Patent Application No. 3112861
It is listed in the issue. In the method described here,
Although symmetrical derivatives of the general formula can be prepared in good yields, their practical importance lies in the radical R 5
and R 6 are lowered when used to prepare compounds of different general formulas. In this case, mutual regioisomers are obtained and, as a result of isolation difficulties, the yield of isolated product is often low. The method of the present invention is regiospecific, eliminates the above-mentioned difficulties, and is based on the instability of the desired carbodiimide, which cannot be obtained by the conventional method described in JP-A-56-156279. It has proven to be the most practical as it allows the production of certain biologically active compounds. The following examples are illustrative of the invention, but are not intended to limit it thereto. Example 1 6-allyl-8β-[1-ethyl-3-(3-dimethylaminopropyl)-ureidocarbonyl]
Ergoline: R 1 = R 2 = R = H, R 4 = Allyl R 5 = (CH 3 ) 2 N-CH 2 CH 2 CH 2 , R 6 = C 2 H 5 6-allyl-8β- in 1000 ml of toluene A mixture of 20 g (3-dimethylaminopropyl-carbamoyl)-ergoline (melting point 198-200 DEG C.) and 150 ml ethyl isocyanate is refluxed for 72 hours. The resulting solution was distilled at 70-80 °C and a pressure of 300 mm,
The residue is applied to a chromatography column packed with 60 g of silica gel (0.05-0.2 mm) and eluted with acetone. The eluent fractions shown to contain the product were collected and the solvent removed from them under reduced pressure to give 20 g of the title compound as a form whose melting point as the diphosphate was
The temperature was 152-154℃. Example 2 6-allyl-8β-(1-ethylureidocarbonyl)-ergoline: R 1 = R 2 = R 3 = R 5 = H, R 4 = allyl, R 6 =
C 2 H 5 6-allyl-8β-carbamoyl-ergoline (melting point 190
Working as described in Example 1 using 210-212 DEG C.), the title compound (mp 210-212 DEG C.) was obtained in 90% yield. Example 3 6-allyl-8β-(1,3-dimethylureidocarbonyl)-ergoline: R 1 = R 2 = R 3 = H, R 4 = allyl, R 5 = R 6 =
CH 3 As described in Example 1, using 6-allyl-8β-methylcarbamoyl-ergoline instead of 6-allyl-8β-(3-dimethylaminopropyl-carbamoyl)-ergoline and using methyl isocyanate instead of ethyl isocyanate. The title compound (melting point 106-108°C) was obtained in a yield of 87%.
