Isopropylamine → 2-[6-[3-Chloro-5-fluoro-4-(trifluoromethyl)phenoxy]benzotriazol-1-yl]propanoic acid;propan-2-amine

Participants

Reaction Steps

Isopropylamine (0.5 g, 0.0085 mole) is added to a solution of 6-[(2-chloro-α,α,α,6-tetrafluoro-p-tolyl) oxy]-α-methyl-1H-benzotriazole-1-acetic acid (2.0 g, 0.005 mole) in methylene chloride and the resultant solution is concentrated in vacuo to afford a gum which is dissolved in toluene. The toluene solution is concentrated to afford the title compound as a white solid, mp 103.5°-105.5°, identified by elemental and NMR analyses.
