実験手順

Pipemidic acid (25 mg, 0.0824 mmol), 3-(trifluoromethyl)phenyl isothiocyanate (12.5 μL, 0.0824 mmol) and triethylamine (23 μL, 0.165 mmol) were used. Purification on silica yielded compound 11 in Table 1, below (31 mg, 75%). 1H NMR (300 MHz, CDCl3) δ 9.32 (s, 1H), 8.72 (s, 1H), 7.41-7.35 (m, 1H), 7.29-7.21 (m, 2H), 7.21-7.16 (m, 1H), 4.37 (q, J=7.10 Hz, 2H), 4.27-3.93 (m, 8H), 1.50 (t, J=7.04 Hz, 3H) ppm.
