Versuchsvorschrift

A suspension of 2.1 g (5.77 mmol) of (E)-N-(4′-chlorobiphenyl-4-yl)-3-(4-hydroxymethylphenyl)acrylamide in 100 mL of dichloromethane is combined with 1.7 mL (12.19 mmol) of triethylamine and then combined with 0.46 mL (5.88 mmol) of methanesulfonic acid chloride. The reaction mixture is stirred for 3 hours at ambient temperature, diluted with water, and extracted several times with dichloromethane. The combined organic phases are dried over sodium sulfate, filtered through silica gel, and the filtrate is evaporated down. Yield: 0.4 g (18.1% of theory); C22H17Cl2NO (M=382.29); calc.: molecular ion peak (M+H)+: 381/383/385; found: molecular ion peak (M+H)+: 381/383/385.
