4-Isopropylaniline → HCID 57429432, compound

Participants

Reaction Steps

A mixture of ethyl 2-(bromomethyl)-5-chlorobenzoate (0.553 g, 1.99 mmol), 4-isopropylaniline (0.269 g, 1.99 mmol) and sodium ethoxide (0.406 g, 5.97 mmol) in ethanol (40 mL) was heated at reflux overnight. After this time, the mixture was cooled to room temperature and concentrated under vacuum. The mixture was partitioned between 1 N HCl and ethyl acetate. The organic layer was separated, washed with 1 N HCl, then with 1:1 water/brine solution, dried over sodium sulfate and filtered. Concentration under vacuum and recrystallization from ethyl acetate afforded 6-chloro-2-(4-isopropylphenyl)isoindolin-1-one (0.302 g, 53%) as an off-white solid: m.p. 206-209° C.; 1H NMR (500 MHz, CDCl3) δ 7.89 (d, J=1.9 Hz, 1H), 7.73 (dt, J=8.6, 2.7 Hz, 2H), 7.55 (dd, J=8.1, 1.9 Hz, 1H), 7.45 (d, J=8.0 Hz, 1H), 7.30 (dt, J=8.5, 2.5 Hz, 2H), 4.83 (s, 2H), 2.96-2.90 (m, 1H), 1.26 (d, 6H); ESI MS m/z 286 [M+H]+.
