実験手順

To an ice cold solution of 5.5 g. (33 mmole) 4-(2-hydroxyethyl)-phenethylamine, 100 ml. methylene chloride and 3.4 g. (33 mmole) triethylamine is slowly added dropwise a solution of 7.2 g. (33 mmole) 4-azidobenzenesulphonyl chloride in 50 ml. methylene chloride. Subsequently, the reaction is allowed to continue for 1 hour with ice cooling. The reaction mixture is now shaken out twice with dilute sulphuric acid, then twice with water, dried with anhydrous sodium sulphate and finally evaporated. The residue is recrystallised twice from toluene to give 7.8 g. (64% of theory) of desired product; m.p. 90°-92° C. (recrystallised from toluene).
