- Preparation method of 4', 6-diamidinyl-2-phenylindole dihydrochloride
-
The invention discloses a preparation method of 4', 6-diamidinyl-2-phenylindole dihydrochloride, which comprises the following steps: firstly, taking 6-substituted indole as a raw material, and reacting with formamide under the action of a reaction solvent and a first catalyst to prepare 6-cyano indole; then performing a reactionthe 6-cyanoindole and the 4-substituted cyanobenzene under the action of a second catalyst, and obtaining 6-cyano-2-(4 '-cyanophenyl) indole; using 6-cyano-2-(4'-cyanophenyl) indole as a raw material and reacting with alcohol containing a substituent group under the action of a third catalyst, and obtaining 4', 6-bis (substituent group-containing methyleneimic acid ester)-2-phenylindole dihydrochloride; finally, continuously reacting with ammonium chloride, and obtaining the 4', 6-diamidinyl-2-phenylindole dihydrochloride. The design route is reasonable in design, the process safety is high, the method is friendly to operators, the cost is low, and the requirement for industrial production of products can be fully met.
