Participants

Reaction Steps

A solution of the title E compound, 2-benzyloxy-5-(2,6-dimethyl-4-nitrophenoxy)-benzenesulfonyl chloride (1.12 g, 2.5 mmol) in 20 mL of CH2Cl2 is treated sequentially with N-methylmorpholine (NMM; 550 mL, 5 mmol) and neopentylamine (442 mL, 3.75 mmol) at RT. After 6 h, the mixture is partitioned between water and EtOAc, and the organic solution is washed with aqueous 1N HCl and brine, dried over anhydrous Na2SO4 and concentrated to afford 2-benzyloxy-5-(2,6-dimethyl-4-nitrophenoxy)-N-(2,2-dimethylpropyl)benzenesulfonamide: NMR (CDCl3) 0.78 (s, 9H), 2.22 (s, 6H), 2.58 (d, 2H, J=7.5), 4.82 (t, 1H, J=7.5), 5.18 (s, 2H), 6.88 (dd, 1H, J=9, 3.7), 7.03 (d, 1H, J=9), 7.33-7.51 (m, 6H), 8.04 (s, 2H).
