Extracurricular laboratory: Synthetic route of 202925-10-8

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 202925-10-8, (4-Chloro-3-fluorophenyl)methanol.

Reference of 202925-10-8, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 202925-10-8, name is (4-Chloro-3-fluorophenyl)methanol. This compound has unique chemical properties. The synthetic route is as follows.

Example 229 4- ( (4-Chloro-3-fluorobenzyl) oxy) -1- (2-ethyl-l-methyl-lH- benzimidazol-6-yl) yridin-2 ( 1H) -one To a solution of 1- (2-ethyl-l-methyl-lH-benzimidazol-6- yl) -4-hydroxypyridin-2 ( 1H) -one (500 mg) , (4-chloro-3- fluorophenyl) methanol (596 mg) and tributylphosphine (1.13 g) in THF (20 ml) was added 1, 1′ – (azodicarbonyl) dipiperidine (1.41 g) , and the reaction mixture was stirred at 60C for 2 h. The reaction mixture was cooled to room temperature. The mixture was poured into water and extracted with EtOAc. The extract was washed with brine, dried over MgS04, concentrated and purified by NH silica gel column chromatography (hexane/EtOAc then EtOAc/MeOH) . ‘The resulting solid was recrystallized from EtOH-water to give the title compound (265 mg) as a white solid. MS (ESI+) : [M+H] + 412.3. 1H NMR (400 MHz, DMSO-d6) : delta 1.33 (3H, t, J = 7.5 Hz), 2.90 (2H, q, J = 7.5 Hz), 3.74 (3H, s) , 5.18 (2H, s), 5.97 (1H, d, J = 2.6 Hz), 6.12 (1H, dd, J = 2.4, 7.5 Hz), 7.07 (1H, d, J = 8.4 Hz), 7.35 (1H, d, J = 8.5 Hz), 7.52-7.57 (2H, m) , 7.60 (2H, dd, J = 4.8, 7.8 Hz), 7.66 (1H, t, J = 8.2 Hz).

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 202925-10-8, (4-Chloro-3-fluorophenyl)methanol.
