Reference of 796729-10-7, The chemical industry reduces the impact on the environment during synthesis 796729-10-7, name is 5,6-Dihydro-4H-pyrrolo[1,2-b]pyrazole-3-carboxylic acid, I believe this compound will play a more active role in future production and life.
Add 5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole-3-carboxylic acid (0.81 g, 5.3 mmol) and 15 mL of 1,4-dioxane, benzyl alcohol to a 50 mL single-mouth vial (0.83 mL, 8.0 mmol), DIPEA (1.8 mL, 11.0 mmol), and DPPA (2.20 g,8.0 mmol), refluxing at 110 C overnight, the reaction was completed by TLC, cooled to 0 C, suction filtration,Obtained 0.98 g of a pale yellow solid in a yield of 72%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5,6-Dihydro-4H-pyrrolo[1,2-b]pyrazole-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.
