Reaction Steps

A 1.0 g quantity of 1-diazo-2-pentanone is dissolved in 50 ml of chloroform, and 2.2 g of o-toluenesulfonic acid is slowly added to the solution. The same procedure as in Example 1 is thereafter repeated to afford 1.37 g of 2-oxopentyl-o-toluene sulfonate in the form of a transparent colorless oil (Compound 29).
