Participants

Reaction Steps

Take up vanillin (1.0 g, 6.57 mmol), 6-chloronicotinonitrile (0.911 g, 6.57 mmol) and K2CO3 (1.36 g, 9.86 mmol) in DMF (16.4 mL). Stir at room temperature overnight, then heat at 100° C. for 3 hours. Cool the reaction mixture to room temperature before quenching with water (75 mL). Extract with dichloromethane (2×150 mL). Wash the organic layer with brine (1×75 mL), dry over MgSO4, filter and concentrate to give the title compound (1.65 g, 98.8%): TOF MS ES+ 255.1 (M+H)+, HRMS calcd for C14H11N2O3 255.0770 (M+H)+, found 255.0776, time 0.38 min; HPLC [YMC-Pack Pro C-18 (150×4.6 mm, S-5 microm), 0.1% TFA/acetonitrile in 0.1% TFA/water at 1.0 mL/min, 20-99% over 23 min], tR=12.2 min, 100% purity.
