실험 절차
3-Chloropropanol (47.3 g, 0.50 mole) and a catalytic amount of triethylamine at 65° C. were treated dropwise with 42 g (0.50 mole) of diketene. After the addition was complete, the reaction was stirred at 65° C. for an additional hour. Distillation of the residue furnished 72.9 g (82%) of product as a clear liquid, b.p. 78°-85° C. at 150 mm. Additional Formula II intermediates can be prepared by modifications of the above examples which would be understood by one skilled in the art of organic chemical synthesis.
