By the procedure of Example 50 the product of Example 18 (3.8 g) and 1,3,5-tributyl-4-methylamino-1,2,4-triazolium chloride (5.7 g) were mixed and the resulting sodium chloride filtered off. The filtrate was evaporated in vacuo and the residual oil treated with acetone. Unreacted phosphinate (0.3 g) was filtered off and the filtrate evaporated in vacuo, finally at the oil pump, to give the required salt as an amber oil (6.0 g). The nmr spectrum was in agreement with the structure.
