Adding a certain compound to certain chemical reactions, such as: 121507-34-4, name is 5-Isopropoxy-1H-pyrazol-3-amine, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 121507-34-4, COA of Formula: C6H11N3O
6-chloro-N’-(5-isopropoxy-1H-pyrazol-3-yl)-N-[(3-methylisoxazol-5-yl)methyl]pyrimidine-2,4-diamine (also known as 6-chloro-N-[(3-methyl-1,2-oxazol-5-yl)methyl]-N’-(5-propan-2-yloxy-1H-pyrazol-3-yl)pyrimidine-2,4-diamine), used as starting material, was prepared as follows: a) A solution of 2,4,6-trichloropyrimidine (1.3 g, 7.08 mmol) and sodium carbonate (0.751 g, 7.08 mmol) in ethanol (20 ml) was cooled to 0 C. and then 5-isopropoxy-1H-pyrazol-3-amine (1.0 g, 7.08 mmol) was added. The mixture was stirred at room temperature overnight and then evaporated. The residue was taken up in ethyl acetate (50 ml) and washed with water (50 ml) and then with brine (25 ml). The organic extracts were dried over magnesium sulfate, filtered and then evaporated to leave a yellow oil. The oil was purified by chromatography on silica eluting with a mixture of 25-60% ethyl acetate in iso-hexane. The fractions containing product were combined and evaporated to leave a solid that was triturated with diethyl ether to give 2,6-dichloro-N-(5-isopropoxy-1H-pyrazol-3-yl)pyrimidin-4-amine (1.06 g, 52% yield). 1HNMR(400 MHz, DMSO 373K): 1.31 (d, 6H), 4.5 (bs, 1H), 5.62 (s, 1H), 7.19 (bs, 1H), 10.16 (bs, 1H), 11.72 (bs, 1H).MS: m/z 288 (MH+).
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-Isopropoxy-1H-pyrazol-3-amine, other downstream synthetic routes, hurry up and to see.
