Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39065-95-7, name is 4-(Chlorodifluoromethoxy)aniline, This compound has unique chemical properties. The synthetic route is as follows., Formula: C7H6ClF2NO
[00713] 6-Chloro-5-iodo-3-pyridinecarboxylic acid (18 g, 62.2 mmol) was suspended in toluene (125 mL). DMF (1.446 mL, 18.67 mmol) and SOCl2 (13.63 mL, 187 mmol) were added at RT. The RM was stirred at 80C for 1 h, cooled to RT then the solvent was evaporated off under reduced pressure to give a residue that was dissolved in THF (125 mL) and cooled to – 15C. DIPEA (21.74 mL, 124 mmol) was added at -15C, and the cold mixture was treated dropwise with a solution of 4-(chlorodifluoromethoxy)aniline in THF (125 mL) over 12 min. The resulting fine orange suspension was stirred for 1 h at RT. The solvent was evaporated off under reduced pressure and the residue was dissolved in TBME (500 mL),and sequentially washed with IN HC1 (2 x 150 mL), sat. aq. NaHC03 solution (2 x 150 mL) and brine (2 x 150 mL). The aq. phases were extracted with TBME (400 mL). Combined organic phases were dried over Na2S04, filtered and concentrated under reduced pressure until crystallization began (around 100 mL). n- Heptane (800 mL) was then added with stirring and the light yellow suspension was stirred at RT for 30 min. The crystalline product was filtrated , washed with n-heptane (200 mL) and dried to afford the title product as a beige solid. LC-MS (Condition 3) tR 1.25 min, 459.0/460.7/462.1
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 39065-95-7.
