Yield:7012-16-0 40.9%
Reaction Conditions:
with chlorine;acetic acid at 40; for 2 h;
Steps:
1 Example 1: Fluorene chloride
1200 mL of glacial acetic acid, 166.2 g (1 mol) of hydrazine (I) and a 2500 mL four-necked flask were maintained to maintain an internal temperature of 40 ° C.The chlorine gas was introduced under the right mechanical stirring, and the reaction was detected by high performance liquid chromatography until the basic reaction of 2-chloroindole was completed. Stop chlorine,Stir at 40 ° C for 2 h, warm to reflux until the reaction solution is completely soluble, cool to room temperature, filtered, solid 2,7-dichloropurine, after drying98 g, liquid phase content of 98.2% (0.409 mol), yield 40.9%. The mother liquor is a yellow transparent liquid, which is detected by liquid chromatography.The contents of the relevant components are shown in Table 1.
