Reaction Steps

A solution of 2-((4S)-3-(4-(4-chlorophenoxy)phenyl)-2-oxo-4-(3-(2-(tetrahydro-2H-pyran-2-yloxy)ethoxy)phenyl)imidazolidin-1-yl)-N,N-bis(4-methoxybenzyl)-ethane-sulfonamide (40 mg, 0.046 mmol) in TFA (1 mL) is stirred at room temperature for 2 h and is then concentrated. The residue is dissolved in MeOH (1 mL) and NaOH (0.09 mmol, 1M aqueous solution) is added. The mixture is stirred at room temperature for 14 h and is treated with water (3 mL) and extracted with EtOAc (3×3 ml). The combined organic layers are concentrated and purified by flash column chromatography (silica gel, 0-100% EtOAc/hexane) to provide the title compound as a white solid (20 mg, 81%). 1H NMR (CDCl3, 400 MHz) δ 7.21-7.28 (m, 5H), 6.81-6.97 (m, 7H), 5.67 (s, 2H), 5.16 (dd, J=9.2, 6.8 Hz, 1H), 3.98-4.08 (m, 2H), 3.92 (m, 3H), 3.75-3.80 (m, 2H), 3.26-3.41 (m, 3H), 2.37 (br s, 1H); HPLC-MS calculated for C25H26ClN3O6S (M+H+) 532.1, found 532.1.
