4-Methylbenzyl alcohol → HCID 21890199, compound

Participants

Reaction Steps

4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]aniline (129 mg) was added to toluene/triethylamine=10/1 (10 ml), and the mixture was heated under reflux to prepare a solution. A solution of triphosgene (193 mg) in methylene chloride was then added to the solution, and the mixture was heated under reflux for 15 min. Subsequently, 4-methylbenzyl alcohol (79 mg) was added thereto, and the mixture was further stirred with heating under reflux for 2 hr. After the completion of the reaction, the reaction solution was allowed to cool to room temperature before distilled water was added thereto. The mixture was subjected to separatory extraction with chloroform, followed by washing with a 1 N aqueous hydrochloric acid solution and saturated brine. The washed solution was dried over sodium sulfate and was concentrated, and the residue was purified on a column using chloroform/methanol to give the title compound (108 mg, yield 51%).
