Procedure

A solution of 54 parts of dimethyl methoxycarbonylphosphonate and 38 parts of 1,1,3,3-tetramethylguanidine in 1000 parts of anhydrous tetrahydrofuran was refluxed for one hour. The solvent was removed under reduced pressure to yield 77 parts of dimethyl 1,1-bis(dimethylamino)-methyleneaminocarbonylphosphonate, nD27 = 1.4855.
