VP (3,3,5-Trimethylcyclohexyl 3-pyridyl methylphosphonate), also known as EA-1511, is an extremely toxic organophosphate nerve agent of the V-series.

Agent VP belongs to a class of organophosphates known as 3-pyridyl phosphonates. These agents are extremely potent acetylcholinesterase inhibitors.[2]

Synthesis

Methylphosphonic dichloride and triethylamine are dissolved in benzene. 3,3,5-Trimethylcyclohexanol
is then slowly added while stirring and cooling. The reaction temperature is maintained at 10-15 °C. The mixture is then heated to 40 °C for 1 hour. A benzene solution of 3,3,5-trimethylcyclohexyl methylphosphonochloridate is formed.

Triethylamine is then added to reaction mixture and

methyl iodide, to produce a water-soluble agent.[2]
