Application of 445-26-1, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.445-26-1, name is 1-(2-Fluorophenyl)ethanol, molecular formula is C8H9FO, molecular weight is 140.1549, as common compound, the synthetic route is as follows.
Example 125 1-(2-Fluorophenyl)ethyl N-{4-[(6,7-dimethoxy-4-quinazolinyl)oxy]phenyl}carbamate 4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]aniline (90 mg) was added to toluene/triethylamine = 10/1 (9 ml), and the mixture was heated under reflux to prepare a solution. A solution of triphosgene (136 mg) in methylene chloride was then added to the solution, and the mixture was heated under reflux for 15 min. Subsequently, 2-fluoro-alpha-methylbenzyl alcohol (55 mg) was added thereto, and the mixture was further stirred with heating under reflux for 2 hr. After the completion of the reaction, the reaction solution was allowed to cool to room temperature before distilled water was added thereto. The mixture was subjected to separatory extraction with chloroform, followed by washing with a 1 N aqueous hydrochloric acid solution and saturated brine. The washed solution was dried over sodium sulfate and was concentrated. The residue was purified on a column using chloroform/methanol to give the title compound (79 mg, yield 52%). 1H-NMR (CDCl3, 400 MHz): 8.74 (1H, s), 8.06 (1H, s), 7.58 (1H, s), 7.54 (2H, d, J = 9.0 Hz), 7.39 – 7.43 (1H, m), 7.23 – 7.32 (1H, m), 7.12 – 7.17 (3H, m), 7.03 – 7.08 (1H, m), 6.86 (1H, s), 6.14 (1H, q, J = 6.6.Hz), 4.15 (3H, s), 4.09 (3H, s), 1.62 (3H, d, J = 6.6 Hz) Mass spectrometry value (ESI-MS, m/z): 464 (M++1)
Statistics shows that 445-26-1 is playing an increasingly important role. we look forward to future research findings about 1-(2-Fluorophenyl)ethanol.
