Reaction Conditions

Reaction Steps

Crude product from example C4 is dissolved in dry DMF (180 mL). After addition of sodium azide (11.7 g; 180.0 mmol) the reaction mixture is stirred for three days at 60° C. After filtration the reaction mixture is concentrated under reduced pressure, diluted with dichloromethane, extracted with water, half saturated brine and dried over MgSO4. After column chromatography on silica gel (cyclohexane/AcOEt—9:1) 11.8 g of the title compound is obtained as pale yellow oil.
