Procedure
0.10 mL (41 mmol) benzenesulphonic acid chloride were slowly added to a solution of 0.20 g (41 mmol) (R)-1-(3-amino-4-benzyloxyphenyl)-2-[1,1-dimethyl-3-(4-phenylimidazol-1-yl)-propylamino]-ethanol in 5 mL pyridine at 0° C. with vigorous stirring. After the addition was complete the reaction mixture was stirred for 4 h at 0° C. and then poured into 40 mL ice water/ethyl acetate (1:1). The phases were separated and the aqueous phase was extracted three times with 20 mL ethyl acetate. The combined organic phases were dried over magnesium sulphate and the solvent was removed using the rotary evaporator. 0.14 g (0.28 mmol, 99%) (R)—N-(2-benzyloxy-5-{2-[1,1-dimethyl-3-(4-phenylimidazol-1-yl)-propylamino]-1-hydroxyethyl}-phenyl)-benzenesulphonamide was obtained as a white solid.
