Reaction Conditions

Reaction Steps

A mixture of 2,6-difluoroaniline (0.5 g, 3.9 mmol), TMSCN (0.72 mL, 5.8 mmol), and cyclobutanone (0.43 mL, 5.8 mmol) was heated to 90° C. overnight. The mixture was poured in water and the aqueous layer was extracted with EtOAc (3×). The organics were combined, washed with brine. (2×), dried over sodium sulfate, and evaporated to dryness. The residue was purified by column chromatography on silica gel eluting with 0 to 20% EtOAc/hexanes to afford 0.7 g of 1-((2,6-difluorophenyl)amino)cyclobutanecarbonitrile as a colorless oil. 1H NMR (300 MHz, DMSO-d6) δ 7.07-7.01 (m, 2H), 6.91-6.81 (m, 1H), 6.15 (s, 1H), 2.65-2.56 (m, 2H), 2.52-2.42 (m, 2H), 2.01-1.91 (m, 2H).
