Adding a certain compound to certain chemical reactions, such as: 741717-59-9, name is 2-(1-Pyrazolyl)benzyl Alcohol, 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 741717-59-9, HPLC of Formula: C10H10N2O
To a solution of DMSO (670 mg, 8.56 mmol) in anhydrous DCM was added oxalyl chloride (220 mg, 1.73 mmol) at -70 C under nitrogen atmosphere and the mixture was stirred for 30 mm. A solution of X4-095-2 (300 mg, 1.72 mmol) in DCM was then added and stirring was continued at the same temperature for 30 mm before Et3N (1.4 g, 13.9 mmol) was added. After stirring for 20 mm at 0 C the mixture was diluted with DCM (50 ml), and then washed with water (10 ml), 1 M HC1 (10 mL), saturated aq. NaHCO3 solution (10 mL) and brine (10 mL). The organic phase was dried over Na2SO4 and evaporated in vacuo. The residual material was purified by silica gel column chromatography to give X4-164-4b (200 mg, 67%) as a white solid. LCMS (Agilent LCMS 1200-6110, Column: Waters X-Bridge C18 (50 mm*4.6 mm*3.5 jim); Column Temperature: 40 C; Flow Rate: 2.0 mL/min; Mobile Phase: from 95% [water + 0.05% TFA] and 5% [CH3CN + 0.05% TFA] to 0% [water + 0.05% TFA] and 100% [CH3CN + 0.05 % TFA] in 1.6 mm, then under this condition for 1.4 mm, finally changed to 95% [water + 0.05% TFA] and 5% [CH3CN + 0.05% TFA] in 0.05 mm and under this condition for 0.7 mm) Purity: 92%. Rt = 1.495 mm; MS Calcd.: 172.1; MS Found: 173.1 [M + H].
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, 2-(1-Pyrazolyl)benzyl Alcohol, other downstream synthetic routes, hurry up and to see.
