Diethyl Ether → HCID 67943868, compound

Participants

Reaction Steps

Intermediate E (1.0 g) and diphenylformamidine (2.2 g) were combined in a flask and heated over a hot air gun with manual stirring until a yellow-orange color formed. The reaction was then heated for 1 minute at full heat until it became totally liquid. On cooling to room temperature, the reaction mixture solidified. This solid was dissolved in 20 ml hot acetone, poured into 100 ml diethyl ether with stirring, and stirred for 1 hour. The solid was then filtered out and washed with diethyl ether to give 1.2 g of 2-(2-anilinovinyl)-3-ethyl-5-methylsulfonamidobenzoxazolium iodide (Intermediate F).
