Sodium Azide → HCID 22106522, compound

Participants

Reaction Steps

Trifluoromethane sulfonic anhydride (9.42 ml) was added dropwise over 10 min to a solution of cyclopropanecarboxylic acid(4-benzyloxy-phenyl)-amide (15 g) and sodium azide (3.64 g) in acetonitrile (250 ml) at 0°. The reaction mixture was stirred at room temperature under nitrogen for 16 h. 10% Aqueous sodium hydrogen carbonate (80 ml) was added and the organic layer was separated. The aqueous layer was further extracted with ethyl acetate (2×100 ml). The combined organic parts were dried over anhydrous sodium sulphate and concentrated in vacuo to give a brown oil. Purification by chromatography with ethyl acetate:isohexane (1:1) as eluant afforded the title compound (2.4 g) as a yellow solid, m.p. 118°.
