Employing the procedure essentially as described in Example 1 using 6-[3-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-phenylsulfanyl]-nicotinonitrile (430 mg, 1.03 mmol), sodium azide (668 mg, 10.3 mmol), and triethylamine hydrochloride (1.41 g, 10.3 mmol) purify by reverse phase chromatography eluting with methanol: acetic acid: water, the title compound is obtained as a white solid (77 mg, 16%): 1H NMR (CD3CN) δ 0.83 (t, 3H), 1.48 (sextuplet, 2H), 2.53 (s, 3H), 2.60 (t, 2H), 5.24 (s, 2H), 6.62 (d, 1H), 7.11 (d, 1H), 7.56 (m, 3H), 7.71 (m, 2H), 8.11 (dd, 1H), 8.96 (dd, 1H), 12.82 (bs, 1H); MS (esi negative) m/z 460 (m−1).
