Reaktionsschritte
To a solution of 2-Chloro-6-methyl-isonicotinic acid (1 g) in DMF (200 ml) at 25° C. was added DIPEA (2.9 mL) and TBTU (1.8 ml). After 5 min, dimethylamine (0.75 g) was added dropwise. This was stirred overnight. The reaction was added to water and extracted with EtOAc. The organic layer was separated, dried and concentrated in vacuum. Flash chromatography (9:1 to 2:8 gradient cyclohexane:EtOAc) afforded the title compound (320 mg). Rf=0.56 (1:1 cyclohexane:EtOAc)
