Reaction Conditions:
with triethylamine;tris[tert-butyl]phosphonium tetrafluoroborate in tetrahydrofuran;water at 20; for 15 h;Staudinger Azide Reduction;
Steps:
A typical procedure for reduction of aromatic azide 8
General procedure: To a solution of ethyl 4-azidobenzoate (8a) (19.0 mg, 99.4 μmol) and NEt3 (16.3 μL, 0.116 mmol) dissolved in THF (0.40 mL) and H2O (40 μL) was added n-Bu3P·HBF4 (34.8 mg, 0.120 mmol) at room temperature. After stirring for 15 h at the same temperature, the mixture was concentrated under reduced pressure. The residue was purified by preparative TLC (n-hexane/EtOAc = 1/1) to give 4-(ethoxycarbonyl)aniline (9a) (15.5 mg, 93.8 μmol, 94.3%) as a colorless oil.
