Participants

Reaction Steps

To a solution of Example 96B (100 mg, 0.349 mmol) in dry dichloromethane (2 mL) was added (4-chlorophenyl)methanesulfonyl chloride (118 mg, 0.524 mmol) and triethylamine (212 mg, 2.096 mmol). The mixture was stirred at room temperature for 16 hours and then concentrated. The residue was purified via HPLC (Gilson®, XBridge™ 30×100 mm column, eluted with pH=10 aqueous ammonium bicarbonate-ammonium hydroxide/methanol, UV=254 nm) to give the title compound as the first eluting diastereomer. 1H NMR (500 MHz, methanol-d4) δ 1.57-1.66 (m, 1 H), 1.91-1.99 (m, 1 H), 2.21-2.29 (m, 2 H), 2.34 (q, 1H, J=8 Hz), 2.62 (dd, 1H, J=12, 10 Hz), 2.92 (td, 1H, J=12, 3 Hz), 3.00-3.06 (m, 2 H), 3.41 (td, 1H, J=9, 6 Hz), 4.33-4.40 (m, 3 H), 4.52 (dd, 1H, J=12, 1 Hz), 6.98 (t, 2H, J=7 Hz), 7.38-7.41 (m, 2 H), 7.44-7.48 (m, 2 H), 7.66-7.72 (m, 1 H); MS (DCI) m/z 475 (M+H)+.
