Reaction Steps

A 1.2 g quantity of 1-diazo-2-pentanone is dissolved in 50 ml of ether, and 2.3 g of benzenesulfonic acid monohydrate is slowly added to the solution at room temperature. The same procedure as in Example 1 is thereafter followed to give 2.0 g of 2-oxopentylbenzene sulfonate in the form of a colorless transparent oil (Compound 6). Yield 77.2%.
