Yield:25948-15-6 91%
Reaction Conditions:
at 20; for 1 h;
Steps:
90.1 Step 1:
2-chloro-5-nitropyridine (4.0 g) was stirred with 2-methylaminoethanol (20 mL) at room temperature for 1 h. The reaction mixture was diluted with water (30 mL) and extracted with ethyl acetate (50 mL x 2), washed with brine (20 mL), dried over Na2S04 and evaporated under vacuum. The residue was washed with n-pentane (25 mL) to get 2-(methyl(5- nitropyridin-2-yl)amino)ethanol (4.5 g, 91 %, yellow solid). TLC system: methanol/chloroform (1 :19), Rf: 0.4.
