Reference of 1445-39-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 1445-39-2, name is 2-Amino-5-iodopyrimidine, molecular formula is C4H4IN3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
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 (Fig. 1-8, Step 2).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 1445-39-2, 2-Amino-5-iodopyrimidine.
