Reaction Steps

While cooling a mixture of 12.0 g of 5-nitrosalicylaldehyde and 100 ml of chloromethyl methyl ether in an ice bath, 43.9 g of anhydrous aluminum chloride was added in small portions to the mixture, followed by stirring at room temperature for 10 minutes and thereafter by refluxing with heating for 22 hours. The reaction mixture was then cooled in an ice bath, and 200 ml of water was added to the mixture with full stirring, whereby white crystals were separated out. The white crystals were collected and dissolved in hot hexane, and the solution was filtered. The mother liquor was thereafter cooled, giving 14.9 g of 3-chloromethyl-5-nitrosalicylaldehyde in the form of white needlelike crystals (yield 72%).
