Tert-butyl 3-nitrobenzoate → tert-Butyl-3-aminobenzoate

Participants

Reaction Steps

1H (CDCl3, 400 MHz) δ 1.4 (9H, s), 7.6 (1H, dd), 8.3 (1H, d), 8.4 (1H, d), 8.8 (1H, s) ppm. A solution of t-butyl 3-nitrobenzoate (5.8 g, 26 mmol) in EtOH (260 mL) was stirred with 10% palladium-carbon (1.0 g) under an atmosphere of H2 (60 psi) at 23° C. After 4 h, the mixture was filtered and evaporated in vacuo to give t-butyl 3-aminobenzoate (4.0 g, 20.7 mmol) as a white solid.
