Ammonium Chloride → HCID 86709394, compound

Participants

Reaction Steps

Sodium tert-butoxide (62 mg) was added to a dimethyl formaldehyde solution (5 ml) of 4-(2-chloro-4-nitroimidazol-1-yl)-1-{4-[2-(4-trifluoromethoxybenzyl)thiazol-4-yl]phenoxy}butan-2-ol (334 mg), and the mixture was stirred at room temperature. While confirming the progress of the reaction, sodium tert-butoxide (62 mg) was added 3 times, and the resulting mixture was stirred overnight. A saturated ammonium chloride aqueous solution was added to the reaction mixture, and the precipitated solid was sequentially washed with water and diisopropyl ether. The residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:1→ethyl acetate) to afford the title compound as a pale brown powder (69 mg).
