実験手順
To a solution of 4-fluoro-2-nitro benzaldehyde (3.76 g, 25 mmol) in dry MeOH (120 ml), was added isopropyl amine (2.1 ml, 25 mmol) and the mixture stirred for 2 hours at room temperature in Argon atmosphere. Then it was then transferred into a Parr bottle containing 5% Pd on charcoal (246 mg) under Argon and hydrogenated at 30 psi for 18 hours. The suspension was filtered over a celite pad, washed with MeOH and evaporated at reduced pressure to afford (2-amino-4-fluorophenyl)-N-(1-methylethyl)-methylamine as a yellow oil.
