실험 절차

Bromopivalic acid (Example 10(a)) (59.4 g, 328 mmol) was reacted with 2-aminothiophenol (41 g, 328 mmol, freshly distilled) according to the procedure for Example 1(d). Column chromatography yielded the title compound (52.3 g, 232 mmol, 71%). 1H NMR (DMSO-d6) δ 12.44 (br s, 1H); 7.22 (d, 1H); 6.99 (t, 1H); 6.63 (d, 1H); 6.47 (t, 1H); 5.27 (br s, 2H); 2.88 (s, 2H); 1.14 (s, 6H). MS Da/e=226 (MH+), 208 (M-H2O), 180 (M-CO2). Calcd for C11H15NSO2 : C, 58.64; H, 6.71; N, 6.22; S, 14.23. Found: C, 58.41; H, 6.78; N, 6.13; S, 14.29.
