Water → 2-Chloro-N-(6-methyl-pyridin-3-yl)-acetamide

Temperatur

-60 °C

A mixture of 6-methylpyridin-3-amine (1 g) and triethylamine (2.2 mL) in dry THF (20 mL) was stirred and cooled to −60° C. 2-Chloroacetyl chloride (1.567 g) was added via syringe to the stirred mixture forming a yellow suspension. The mixture was stirred at −60° C. until analysis showed complete disappearance of starting material. The reaction slurry was poured into water and the products extracted with ethyl acetate (2×150 ml). The combined organic extracts were dried over magnesium sulphate and concentrated to dryness. The crude brown solid was recrystallised from ether to afford the subtitled compound (700 mg).
