Embodiment Construction
[0021] The implementation process of the present invention will be further elaborated below through specific examples.
[0022] 1. Synthesis of 5,5,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane
[0023] Synthesized according to the method of J.Chem..Soc.Perkin I, 591-593,1975.
[0024] 2. Synthesis of 1-acetyl-5,5,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane
[0025] Dissolve 28.5 grams (0.1 mol) of 5,5,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane in 500 milliliters of dichloromethane, add 20 grams (0.14 mol) anhydrous potassium carbonate, stirred and cooled to 0°C. A solution of 7.9 g of acetyl chloride dissolved in 100 ml of dichloromethane was added dropwise in one hour. After the addition, the temperature was gradually raised to room temperature, and stirring was continued for 3 hours, then heated to reflux for 3 hours, and the reaction was completed and cooled to room temperature. After filtration, the filtrate was concentrated by distil...
