Reaction Steps

To a mixture of diethyl 2-aminoethylphosphonate (8.1 g), triethylamine (9.1 g) and dichloromethane (100 ml) at 5° C. was added nicotinic acid chloride hydrochloride (10.4 g) in small portions over a period of 15 minutes. After being stirred for additional 1.5 hours, the reaction mixture was washed with brine, dried over anhydrous magnesium sulfate, and evaporated in vacuo. The residue was chromatographed on silica gel (10% methanol in chloroform) to give 11.2 g of N-(2-diethoxyphosphorylethyl)-3-pyridinecarboxamide as an oil.
