Adding a certain compound to certain chemical reactions, such as: 35344-95-7, name is 1H-Pyrazole-4-carbaldehyde, 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 35344-95-7, Formula: C4H4N2O
A mixture of 8-(1 -methyl-1 H-indol-6-yl)-quinoxalin-6-ylamine (Intermediate 22) (100.00 mg; 0.34 mmol; 1 .00 eqr.), 1 H-pyrazole-4-carbaldehyde (41.89 mg; 0.44 mmol; 1.30 eg.) and CH3COOH (0.10 ml1.75 mmol; 5.22 eq.) in 1 ,2-dichloroethane (5.00 ml_) under argon at 5¡ãC is stirred for 10 min and next 1 h at rt. After this time, RM is cooled to 5¡ãC and NaBH(OAc)3 (96.80 mg; 0.44 mmol; 1.30 eq.) is added and then RM is stirred at rt overnight. RM is diluted with water and extracted with EtOAc. Combined organic layers are washed with brine, dried over Na2S04, filtered and evaporated. Brown residue is purified by FCC (DCM/MeOH; gradient) and repurified by preparative HPLC. 8-(1 -methyl-1 H-indol-6-yl)-N-(1 H-pyrazol-4- ylmethyl)quinoxalin-6-amine (55.00 mg; yield 46 percent; 99 percent by HPLC) as a yellow solid.
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, 1H-Pyrazole-4-carbaldehyde, other downstream synthetic routes, hurry up and to see.
