Procedure
Allyl bromide (195 mg, 1.63 mmol) and potassium carbonate (372 mg, 2.69 mmol) was added to a solution of 3-(5-chloro-2-methoxy-benzenesulfonylamino)-4-hydroxy-benzoic acid methyl ester (example 30, step 1; 200 mg, 0.538 mmol) in acetone, and the reaction mixture was stirred at 60° C. for 16 h. After cooling, insoluble material was filtered off and the filtrate evaporated to produce 3-[allyl-(5-chloro-2-methoxy-benzenesulfonyl)-amino]-4-allyloxy-benzoic acid methyl ester (243 mg, 100%). Orange solid, MS (ISP)=452.1 (M+H)+.
