Trifluoroacetic acid → 1-(1-Azidocyclohexyl)-3-(methyloxy)benzene

Participants

Reaction Steps

To a solution of 1-[3-(methyloxy)phenyl]cyclohexanol (2.93 g, 14.22 mmol, 1 equiv) in CH2Cl2 (25 ml) under nitrogen at 0° C. was added sodium azide (1.85 g, 28.44 mmol, 2 equiv) then TFA (4.4 ml, 56.89 mmol, 4 equiv) slowly. 40 Ml of CH2Cl2 were then added and the resulting suspension was stirred at room temperature for 16 h then partitioned between Et2O and H2O. The two layers were separated and the organic phase was washed with H2O and a 1N aqueous NaOH solution then dried over MgSO4 and concentrated in vacuo to give 1-(1-azidocyclohexyl)-3-(methyloxy)benzene (D315) (2.78 g, 85%) as a clear oil which was used in the next step without further purification.
