Reaction Steps

Iodotrimethylsilane [(CH3)3SiI] (0.458 g) was added to a suspension of 7-cyclohexyl-N-(4-diethoxyphosphorylmethylphenyl)-3,4-dihydronaphthalene-2-carboxamide (0.5 g) in carbon tetrachloride (10 ml) at 0° C. After stirring at 0° C. for 1 hour and then at room temperature for 15 hours, this mixture was concentrated under reduced pressure. To the residue, methanol (6 ml) was added; this mixture was acidified with 1N HCl and stirred at room temperature for 30 minutes. The resulting crystals were collected by filtration and recrystallized from methanol-water to yield 7-cyclohexyl-N-(4-phosphonomethylphenyl)-3,4-dihydronaphthalene-2-carboxamide (0.28 g, 63%) as pale yellow prisms having a melting point of 203°-205° C.
