6-Chloro-2-methylpyridin-3-amine has been used as a reactant in the preparation of Pyrido[3,2-e][1,4]diazepine derivatives with anti-HIV-1-activity. | [Synthesis]
Step 1: Synthesis of 6-chloro-2-methylpyridin-3-amine (44). 2-Chloro-5-nitro-6-methylpyridine (43, 5 g, 29 mmol) was dissolved in ethanol (20 mL) and concentrated hydrochloric acid was added slowly with stirring. Powdered hydrochloric acid (16.2 g, 289 mmol) and additional concentrated hydrochloric acid (20 mL) were added in batches over 30 minutes at room temperature. After addition, stirring was continued for 30 minutes at room temperature. Upon completion of the reaction, the solvent was removed by distillation under reduced pressure. Water was added to the residue and neutralized with sodium bicarbonate to neutral. Subsequently, ethyl acetate was added for extraction and the two-phase mixture was filtered through diatomaceous earth and washed with ethyl acetate. The organic phase was separated, washed sequentially with water and saturated brine, dried over anhydrous sodium sulfate and concentrated to give the target product 44 (4.1 g, 99% yield) as a yellow solid. | [References]
