Application of 19064-18-7, Adding some certain compound to certain chemical reactions, such as: 19064-18-7, name is (2,6-Difluorophenyl)methanol,molecular formula is C7H6F2O, 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 19064-18-7.
To a solution of 2.71 g of (2,6-difluorophenyl)methanol [CAS No.: 19064-18-7] (18.8 mmol, 1.3 eq.) in 120 ml of 1,2-dimethoxyethane were added 4.86 g of potassium tert-butoxide (43.3 mmol, 3.0 eq.) and the mixture was stirred at RT for 60 min. Subsequently, 2.60 g of 2-amino-3-chloro-5-methylpyrazine hydrochloride [CAS No.: 89182-14-9] (14.4 mmol, 1.0 eq.) were added and the mixture was stirred at 80 C. overnight. After cooling to room temperature, saturated aqueous sodium hydrogencarbonate solution was added and the aqueous phase was extracted three times with dichloromethane. The combined organic phases were washed with saturated aqueous sodium chloride solution, dried with magnesium sulphate, filtered and concentrated. The residue was purified by means of Biotage Isolera (340 g silica gel cartridge, cyclohexane/ethyl acetate gradient, 10%->72% ethyl acetate). 1.77 g of the title compound were obtained (39% of theory; 85% purity). (0942) LC-MS (Method 2): Rt=0.94 min (0943) MS (ESpos): m/z=252 (M+H)+ (0944) 1H-NMR (400 MHz, DMSO-d6): delta [ppm]=2.20 (s, 3H), 5.35 (s, 2H), 5.88 (s, 2H), 7.09-7.23 (m, 2H), 7.37 (s, 1H), 7.46-7.57 (m, 1H).
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. 19064-18-7, (2,6-Difluorophenyl)methanol, other downstream synthetic routes, hurry up and to see.
