Reaction Steps

Benzyl chloroformate (0.45 ml; 3.2 mmol) is added to a suspension of FTY720.HCl (1.03 g, 3 mmol) in 2N NaOH (20 ml). The reaction is kept at RT over night and in order to complete the reaction further benzyl chloroformate (0.9 ml; 6.4 mmol) is added. After 2 days at RT the reaction is acidified with 1N HCl, extracted with methylenechloride and purified on a silica gel column using methylenechloride/methanol/acetic acid50% (9/1/0.125) as mobile phase.
