반응 단계

A mixture of 6.8 ml (0.072 mol) acetic acid anhydride and 2.8 ml (0.072 mol) formic acid is heated for 2 h to 60° C. and thereafter mixed, with cooling at 5° C., with 1.9 g (0.012 mol) trans-4-nitroxycyclohexylamine. One leaves to stir overnight at room temperature, subsequently dilutes with 100 ml ethyl acetate and adds 100 ml of water thereto. After neutralisation with saturated sodium hydrogen carbonate solution, the organic phase is dried with sodium sulphate and distilled off in a vacuum. After trituration with ether, the crystals are filtered off with suction. One obtains 1.5 g of the title compound of the m p 148°-150° C., i.e. 66% of theory.
