Procedure

To a mixture of 5-{1-Ethyl-1-[4-(2-hydroxy-3,3-dimethyl-butyoxy)-3-methyl-phenyl]-propyl}-3-methyl-thiophene-2-carboxylic acid (0.6344 g, 1.52 mmol) and CH2Cl2 (10 mL) is added Et3N (0.85 mL, 6.07 mmol), followed by hydrochloride salt of 2-aminoethylmethylsulfone (0.2416 g, 1.52 mmol), EDCl (0.320 g, 1.67 mmol), and HOBT (0.226 g, 1.67 mmol). The resulting solution is stirred at RT overnight, diluted with CH2C2 (30 mL), washed with 1.0 M HCl (3×20 mL), brine (20 mL), dried over MgSO4, and concentrated. The resulting residue is purified by chromatography (50% EtOAc/Hex) to give the titled compound (0.4042 g, 0.77 mmol, 51%). 1H NMR (CDC3), δ 0.71 (t, J=7.3 Hz, 6H), 1.03 (s, 9H), 2.09 (q, J=7.3 Hz, 4H), 2.21 (s, 3H), 2.42 (d, J=3.0 Hz, 1H), 2.46 (s, 3H), 2.98 (s, 3H), 3.32 (t, J=6.4 Hz, 2H), 3.71 (dt, J=8.9, 2.9 Hz, 1H), 3.84-3.94 (m, 3H), 4.10 (dd, J=9.3, 2.5 Hz, 1H), 6.44 (t, J=5.8 Hz, 1H), 6.59 (s, 1H), 6.73 (d, J=8.4 Hz, 1H), 6.99 (d, J=1.7 Hz, 1H), 7.03 (dd, J=8.7, 2.5 Hz, 1H). LC/MS (m/z): calcd for C27H42NO5S2 (M+H)+:524.8; found: 524.2.
