Reaction Steps
2-isopropylaniline (5.0 mL, 36.1 mmol) was added to 100 mL of diethylether and cooled to 0° C. Butyllithium (18.0 mL of 2.0 M solution in pentane, 36.1 mmol) was added dropwise to the cooled aniline solution, affording a light yellow suspension after complete addition. The slurry was warmed to room temperature and stirred for 2 hours. Toluonitrile (4.23 g, 36.1 mmol) was added slowly resulting in the formation of a bright yellow solution after complete addition. Stirring was continued for 1 hour and the solvent was removed in vacuo. Tetrahydrofuran (150 mL) was added and the mixture was refluxed overnight under argon, yielding a dark orange-brown solution. Distilled water (2.0 mL, 112 mmol) was added and the mixture became a milky yellow solution after stirring for 30 minutes at room temperature. Solid, presumably lithium hydroxide, was removed via aerobic filtration and the remaining solvent was removed in vacuo, to produce a light yellow solid. The solid was slurried in 50 mL of pentane and stirred for 2 hours. Filtration of the slurry yielded 7.56 g (83%) of light yellow solid. 1H NMR (400 MHz, CDCl3): 7.77 (d, 2H), 7.30 (d, 1H), 7.22 (d, 2H), 7.15 (t, 1H), 7.04 (t, 1H), 6.83 (d, 1 H), 4.70 (s, 2H), 3.16 (septet, 1H), 2.40 (s, 3H), 1.19 (d, 6H).
