Procedure

3-(4-Acetylamino-2-hydroxy-benzenesulfonylamino)-N-methoxy-N-methyl-succinamic acid tert-butyl ester (0.40 g, 0.9 mmol) was combined with 2-Quinolin-5-yl-ethanol (0.155 g, 0.9 mmol) and triphenyl phosphine (355 mg, 1.3 mmol) in 15 mL THF. The solution was cooled to 0° C. DEAD (0.21 mL, 1.3 mmol) was added. The reaction was slowly warmed to room temperature, and stirred overnight. The reaction mixture was concentrated in vacuo. The crude product was chromatorgraphed using 1:1 ethyl acetate/hexanes followed by ethyl acetate, and then 10% methanol in ethyl acetate to yield 3-[4-acetylamino-2-(2-quinolin-5-yl-ethoxy)-benzenesulfonylamino]-N-methoxy-N-methyl-succinamic acid tert-butyl ester 450 mg (83%) of an off-white solid. MS (APCI) m/z 601.2 (M+1).
