Related Products of 1613191-73-3, The chemical industry reduces the impact on the environment during synthesis 1613191-73-3, name is Allyl 3,5-diamino-1H-pyrazole-4-carboxylate, I believe this compound will play a more active role in future production and life.
Step 2: 3-allyl 7-tert-butyl 2-amino-5, 6-dihydropyrazolo[l,5-a]pyrido[4,3-d]pyrimidine- 3, 7(8H)-dicarboxylate 4. [00239] A mixture of tert-butyl 3-(l,3-dioxolan-2-yl)-4-oxo-piperidine-l-carboxylate (100 mg, 0.3686 mmol), allyl 3,5-diamino-lH-pyrazole-4-carboxylate (67.15 mg, 0.369 mmol), KOH (5 mg, 0.0891 mmol) in dioxane (2 mL) was stirred at ambient temperature for 18h. The solid that formed was filtered and triturated in Et20 to afford compound 4 as a beige solid (lOOmg, 73%). LC-MS (M+H)+ 334.2; NMR (500 MHz, DMSO-d6) delta 8.85 (s, 1H), 6.37 (s, 2H), 6.00-6.07 (m, 1H), 5.51-5.55 (d, 1H), 5.23-5.26 (m, 1H), 4.75-4.76 (m, 2H), 4.55 (s, 2H), 3.69 (m, 2H), 3.32 (s, 2H), 2.93-2.95 (m, 2H), 1.40 (s, 9H).
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, Allyl 3,5-diamino-1H-pyrazole-4-carboxylate, other downstream synthetic routes, hurry up and to see.
