Procedure

1,4,7,10Tetraaza-13-phosphatricyclo[5.5.1.04,13 ]tridecane is prepared in the absence of a solvent by heating 5.0 g of 1,4,7,10-tetraazacyclododecane and 4.7 g of hexamethylphosphorous triamide together at about 75° C for between two and three hours and subliming the crude product at 75° C. at 0.4 mm. The yield is 5.3 g (92%) of product melting at 106°-108° C.
