Reaction Steps

A solution of (2R)-2-[N-(4-bromohexyl)-N-(4-chlorobenzenesulfonyl)amino]-4-methylpentanoic acid amide (Example 24; prepared as described in Reaction Scheme 1; 0.20 g, 0.44 mmol), Et3N (0.25 mL, 1.7 mmol), and morpholine (150 mg, 1.7 mmol) in CH2Cl2 (2 mL) was stirred at rt for 18 h. The reaction was then concentrated to give a crude white wax which was purified by flash chromatography (SiO2, 85% EtOAc/5% hexanes/10% MeOH) to afford the title compound (112 mg) as a white solid in 54% yield. MS (ESI), (M+H)+ 474.4; 1H NMR (DMSO-d6) δ 7.82 (d, 2H, J=8.0), 7.64 (d, 2H, J=8.0), 7.42 (br s, 1H) 6.99 (s, 1H), 4.25 (m, 1H), 3.51-3.60 (br s, 4H), 3.18-3.41 (m, 2H), 2.25-2.35 (br s, 4H), 2.27 (m, 2H) 1.15-1.62 (m, 9H), 0.80 (d, 6H, J=6.0).
