실험 절차

A stirred solution of ethyl 4,6-dichloronicotinate (1) (10 g, 43.4 mmol), isopropyl amine (8 mL) and DIPEA (8 mL) in DMA (50 mL) were heated at 120° C. in a sealed tube for 3 h. The reaction mixture was concentrated to dryness to remove excess of DMA from the reaction mass. The crude material obtained was purified by column chromatography through silica gel and EtOAC:pet. Ether as eluent to obtain the title compound (2). LC/MS: Acquity BEH C18 2.1×50 mm, 1.8 micron; Solvent A=0.1% TFA in water; Solvent B=0.1% TFA in ACN; gradient 0-100% B over 2 min; retention time: 0.90 min; LCMS (ES-API), m/z 243.7 (M+H).
