2-Amino-2-methyl-1-propanol → 2-(1,1-Dimethyl-2-hydroxyethylamino)-3-nitro-5-(trifluoromethyl)pyridine

Participants

Reaction Steps

To a solution of 2-chloro-3-nitro-5-(trifluoromethyl)pyridine (1 g) in N,N-dimethylformamide (10 mL) was added 2-amino-2-methyl-1-propanol (1.18 g) at 0° C. The mixture was stirred at room temperature for 3.5 hours under nitrogen atmosphere. The mixture was diluted with ethyl acetate and washed successively with water and brine. The organic layer was dried over anhydrous magnesium sulfate and concentrated in vacuo to give 2-(1,1-dimethyl-2-hydroxyethylamino)-3-nitro-5-(trifluoromethyl)pyridine (1.23 g) as a yellow oil.
