Procedure

A solution in acetonitrile (30 ml) of crystalline phosphoric acid (2.0 g) and triethylamine (4.0 g) was added dropwise over 4 hours to a mixture of 2-(trimethylsilyl)-ethanol (3.0 g) and and trichloroacetonitrile (8.6 g) at room temperature. The mixture was left overnight, diluted with acetone (200 ml) and cyclohexylamine (15 ml) was added. The precipitate was collected and recrystallised from water and then ethanol 10% cyclohexylamine to give the cyclohexylammonium salt, (1.3 g) m.p. 252°-255°.
