Procedure
According to the procedure described in Example 113B, 4-(3-methoxy-3-methylbutoxy)-3-(trifluoromethyl)aniline (490 mg, 1.77 mmoles) was dissolved in 20 mL of dry tetrahydrofuran. To this solution was added potassium carbonate (318 mg, 2.30 mmoles) followed by phenyl chloroformate (360 mg, 2.30 mmoles). The mixture was stirred overnight at room temperature, then purified with silica gel chromatography (using a gradient of 0-30% ethyl acetate/hexanes) to afford phenyl 4-(3-methoxy-3-methylbutoxy)-3-(trifluoromethyl)-phenylcarbamate as a yellow oil. 1H NMR (300 MHz, CDCl3) δ 7.58 (m, 2H), 7.40 (m, 2H), 7.35-7.1 (m, 4H), 6.9 (m, 1H), 4.10 (m, 2H), 3.22 (s, 3H), 2.1 (m, 2H), 2.1 (m, 2H).
