Procedure

Subsequently at room temperature, 5.0 g of the 4-isopropyl-1-methylcyclohexylcarbonyl chloride was added dropwise to 150 ml of an ether solution of diazomethane prepared from 15 g of nitrosourea, and the mixture was stirred at room temperature for about 2 hours. The solvent was distilled off from the reaction mixture in a vacuum, quantitatively giving pale yellow oily 1-diazo-2-(4-isopropyl-1-methylcyclohexyl)-2-ethanone (cis:trans=1:1).
