Abstract

3 H). Anal. Calcd for CloHl1Cl2NO4S: C, 38.47; H, 3.55; N, 4.49. Found: C, 38.31; H, 3.63; N, 4.15. Reaction of the polymer 4, n = 3, under the same conditions gave only a trace spot when a TLC of the product was compared with the spot of authentic 8 from 1 and morpholine. Competition of the Hydroxy Sulfonyl Chloride 11 and the 0-Methyl Derivative 15a for Aniline. Aniline (35 mg, 0.38 mmol) and EbN (40 mg, 0.40 mmol) in 5 mL of dioxane was added dropwise (10 ...
