Related Products of 50638-46-5, The chemical industry reduces the impact on the environment during synthesis 50638-46-5, name is 4-Bromo-3-chloroanisole, I believe this compound will play a more active role in future production and life.
Step C: Preparation of a-(2-chloro-4-methoxyphenyl)- 1 -(2,6-difluorophenyl)- 1H- imidazole-5 -methanol; To a mixture of l-bromo-2-chloro-4-methoxybenzene (5.31 g, 24.0 mmol) in tetrahydrofuran (40 mL) cooled in an ice-water bath was added dropwise isopropylmagnesium chloride lithium chloride complex (1.3 M tetrahydrofuran, 18.4 mL, 24.0 mmol) over 15 minutes. The reaction mixture was allowed to warm to ambient temperature (about 20 C) and stirred for 16 h. After 16 h, the reaction mixture was cooled to 0 C and l-(2,6-difluorophenyl)-lH-imidazole-5-carboxaldehyde (i.e. the product of Step B) (2.50 g, 12.0 mmol) in tetrahydrofuran (10 mL) was added dropwise. The reaction mixture was stirred for about 15 minutes, and then saturated aqueous ammonium chloride solution (about 3 mL) was added. After about 5 minutes more saturated aqueous ammonium chloride solution (about 100 mL) was added and the resulting mixture was extracted with ethyl acetate (100 mL). The organic layer was washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered and concentrated under reduced pressure to provide the title compound as a white solid (2.77 g).in NMR (CDCI3): delta 7.51 (s, 1H), 7.43 (m, 1H), 7.38 (d, 1H) 7.1-7.0 (m, 2H), 6.9 (m, 1H), 6.82 (m, 1H), 6.78 (m, 1H), 5.98 (m, 1H), 3.80 (s, 3H), 2.4 (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, 4-Bromo-3-chloroanisole, other downstream synthetic routes, hurry up and to see.
