PROCEDURE

实验过程

112 g (250 mmol) of 2,5-anhydro-3,4-dideoxy-1,6-bis-O-[(4-methylphenyl)sulfonyl]-hexitol from step 1 and 90.7 g (840 mmol) of benzylamine in 500 ml of toluene are heated under reflux for 20 hours. The precipitate is then filtered off with suction and washed with toluene. The combined toluene phases are concentrated in a rotary evaporator and distilled in vacuo. After a benzylamine fore-run, the product is obtained.
