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.1736-74-9, name is 4-(Trifluoromethoxy)benzyl alcohol, molecular formula is C8H7F3O2, molecular weight is 192.1352, as common compound, the synthetic route is as follows.Safety of 4-(Trifluoromethoxy)benzyl alcohol
EXAMPLE 87 4-(trifluoromethoxy)benzyl 1H-indol-4-ylcarbamate [4-(Trifluoromethoxy)phenyl]methanol (0.13 g, 0.7 mmol) and the product of Example 80A (0.1 g, 0.63 mmol) in THF (5 mL) were heated at reflux for 16 hours with a catalytic amount of triethylamine. The reaction mixture was concentrated under reduced pressure and the residue was triturated with diethyl ether/hexane to provide the title compound as tan crystals (0.12 g). 1H NMR (300 MHz, DMSO-d6) delta 5.21 (s, 2H), 6.73 (s, 1H), 7.0 (t, 1H), 7.1 (d, 1H), 7.23 (t, 1H), 7.38 (dd, 1H), 7.4 (d, 2H), 7.6 (d, 2H), 9.5 (s, 1H), 11.06 (s, 1H).). Anal. Calcd. for C17H13N2F3O3.0.25 H2O: C, 57.55; H, 3.84; N, 7.90. Found: C, 57.42; H, 3.81; N, 7.32.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1736-74-9, 4-(Trifluoromethoxy)benzyl alcohol, and friends who are interested can also refer to it.
