Electric Literature of 1445-39-2 ,Some common heterocyclic compound, 1445-39-2, molecular formula is C4H4IN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
, Step 1). 646 mg (corresponding to 3.0 mmol) of 2-bromo-4′-hydroxyacetophenone and 668 mg (corresponding to 3.0 mmol) of 2-amino-5-iodopyrimidine were dissolved in 20 mL of acetonitrile. The resulting solution was refluxed in an oil bath at 110C for 8 hours. After the completion of the reaction, the reaction solution was cooled down to room temperature, and precipitates were filtered and recovered. The precipitates were washed with acetonitrile and dried under reduced pressure. The resulting crude crystals were suspended in a mixed solution of 10 mL of water and 10 mL of methanol. Then, about 15 mL of a saturated sodium hydrogencarbonate solution was added thereto, and the mixture was sonicated for 3 minutes using an ultrasonic washing machine. Precipitates were filtered and recovered from the resulting mixture, sufficiently washed with water, and dried under reduced pressure, to obtain 737 mg (corresponding to 2.19 mmol) of 2-(4′-hydroxyphenyl)-6-iodoimidazo[1,2-a]pyrimidine (
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1445-39-2, its application will become more common.
