The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 1227002-03-0, name is Methyl 2-amino-5-chloroisonicotinate. This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C7H7ClN2O2
To a solution of methyl 2-amino-5-chloroisonicotinate (4.75 g, 25.5 mmol) in DMF (40 mL) was added 4-(dimethylamino)pyridine (0.466 g, 3.82 mmol), triethylamine (10.62 mL, 76 mmol), and di-tert-butyl dicarbonate (16.67 g, 76 mmol). The reaction was stirred at room temperature for 3 d. The reaction was quenched with water (40 mL). The aqueous layer was extracted with EtOAc (100 mL, three times), and the combined organic layers were washed with water, brine, dried (MgS04) and concentrated. The residue was purified by flash chromatography (80 g silica gel column, gradient elution from hexanes to 15% EtOAc/hexanes) to provide bis-Boc aminopyridine (6.36 g, 16.44 mmol) as a white powder.
With the rapid development of chemical substances, we look forward to future research findings about 1227002-03-0.
