実験手順
To a stirred, refluxing mixture of 5.00 g of 2,4,6-trichloropyrimidine in 100 ml of o-dichlorobenzene under nitrogen was added dropwise 26.00 g of methyl diphenylphosphinite. After the addition was completed, the mixture was refluxed for 6.5 hours and then allowed to stand overnight at room temperature. The next day a small amount of the solvent was removed by boiling, and the solution was allowed to stand again overnight. The next day the resulting solid was separated by filtration, washed twice with benzene and three times with hexane, recrystallized from 650 ml of toluene, and dried at 100° C./0.1 mm (13 Pa) to give 11.35 g of 2,4,6-tris(diphenylphosphinyl)pyrimidine (shown by formula in Claim 10) as a white solid, mp 235°-236° C. Anal. Calcd for C40H31N2O3P3 : C, 70.59; H, 4.59; N, 4.12; P, 13.65. Found: C, 70.72; H, 4.90; N, 3.92; P, 13.61.
