Related Products of 161446-90-8, 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 161446-90-8, name is 3-Chloro-4-fluorobenzyl Alcohol. This compound has unique chemical properties. The synthetic route is as follows.
Example 222 4- ( (3-Chloro-4-fluorobenzyl) oxy) -1- (2- ( (1RS,2SR) -2- (2- hydroxypropan-2-yl ) cyclopropyl) -l-methyl-lH-benzimidazol-6- yl) pyridin-2 (1H) -one To a mixture of. 4-hydroxy-l- (2- ( ( IRS, 2SR) -2- (2- hydroxypropan-2-yl ) cyclopropyl) -l-methyl-lH-benzimidazol-6- yl) pyridin-2 (1H) -one (100 mg) , (3-chloro-4- fluorophenyl) methanol (95 mg) , tributylphosphine (0.219 ml) and THF (10 ml) was added 1, 1′ – (azodicarbonyl) dipiperidine (223 mg) , and the mixture was stirred at 60C for 2 h. The reaction mixture was diluted with EtOAc, washed with water and brine successively, dried over MgS04, filtered through a plug of NH silica gel, and concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane/EtOAc then EtOAc/MeOH) , followed by NH silica gel column chromatography (hexane/EtOAc) . Then the resulting solid was recrystallized from IPA-EtOAc to give the title compound (58.4 mg) as an off-white solid. MS (ESI+) : [M+H] + 482.2. XH NMR (400 MHz, DMSO-d6) : delta 1.09 (6H, s) , 1.23-1.32 (1H, m) , 1.36-1.44 (1H, m) , 1.56-1.66 (1H, m) , 2.22-2.31 (1H, m) , 3.86 (3H, s), 5.18 (2H, s) , 5.86 (1H, s) , 5.98 (1H, d, J = 2.3 Hz), 6.13 (1H, dd, J = 2.3, 7.8 Hz), 7.09 (1H, d, J = 8.4 Hz), 7.35 (1H, d, J = 7.9 Hz), 7.51-7.59 (3H, m) , 7.60-7.70 (2H, m) .
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 161446-90-8, 3-Chloro-4-fluorobenzyl Alcohol.
