1-Bromoheptane → HCID 70982000, compound

Participants

Reaction Steps

4,5-Dichloroimidazole (1.23 g, 9 mmol) was dissolved into 27 mL of acetonitrile. Potassium hydroxide (0.61 g, 9.9 mmol) was added and the mixture was allowed to stir for 0.5 h. 1-bromoheptane (1.41 mL, 9 mmol) was added and the solution was allowed to reflux overnight. The solution was filtered hot to remove a white precipitate (presumed to be KBr) and 2-bromomethylnaphthalene (1.98 g, 9 mmol) was added and the mixture was returned to reflux overnight. The mixture was then allowed to cool to room temperature, resulting in a yellow/white precipitate (2.73, 67% yield). 1H NMR (500 MHz, DMSO-d6) 9.70 (1H, s, NCHN), 7.99 (4H, m, Ar), 7.57 (3H, m, Ar), 5.68 (2H, s, NCH2), 4.23 (2H, t, NCH2), 1.82 (2H, tt, CH2), 1.30 (8H, m, CH2), 0.93 (3H, t, CH3). MS: m/z=374.8 (theor for C21H25Cl2N2Br1=456.25).
