Isopropylamine → HCID 57697946, compound

Participants

Reaction Steps

To a solution of 300 mg (2.17 mmol) of 6-aminonicotinic acid in 50 mL of chloroform were added 370 μL (4.34 mmol) of isopropylamine, 4 mL of anhydrous propanephosphonic acid (25 wt % solution in ethyl acetate) and 1.4 mL (10 mmol) of triethylamine, and the mixture was stirred for 6 hours at room temperature. Then, saturated sodium bicarbonate aqueous solution was added to the reaction mixture, and the mixture was extracted with dichloromethane. The organic layer was washed with saturated saline solution and dried over with anhydrous sodium sulfate. The solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (eluent: dichloromethane/methanol=10/1 to 5/1) to give 30 mg (8%) of the title compound.
