These common heterocyclic compound, 151521-41-4, name is 4-Propyl-1H-pyrazol-3-amine, 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. Recommanded Product: 151521-41-4
(A) In the same manner as described in the step (B) of Reference Example 11, 4.5 g of N-(4-n-propyl-1H-pyrazol-3-yl)acetamidoxime was obtained from 7.2 g of 3-amino-4-n-propyl-1H-pyrazole and 9.3 g of triethyl orthoacetate.
The synthetic route of 4-Propyl-1H-pyrazol-3-amine has been constantly updated, and we look forward to future research findings.
