With copper(I) iodide; triethylamine;tetrakis(triphenylphosphine) palladium(0); In N,N-dimethyl-formamide; EXAMPLE 17 This Example illustrates the preparation of diethyl 3(1-trityl-1,2,4-triazol-3-yl)prop-2-yne phosphonate having the structural formula (XVII). A stirred solution of <strong>[151899-62-6]1-trityl-3-iodo-1,2,4-triazole</strong> (26.24 g, prepared as described in Example 5), propargyl alcohol (3.56 ml) and triethylamine (40 ml) in dry N,N-dimethylformamide (750 ml) was treated successively with tetrakis(triphenylphosphine)palladium (2.77 g) and cuprous iodide (1.0 g). It was stirred for four hours at room temperature under nitrogen and allowed to stand overnight but the reaction had not proceeded to completion. Stirring was continued for a further four periods of seven hours, then the mixture was poured into water (11) and extracted with chloroform (5*250 ml). The extracts were dried over magnesium sulphate, evaporated under reduced pressure and chromatographed on silica, using ethyl acetate-hexane (4:1) as eluant. Trituration with ether gave 1-hydroxy-3(1-trityl-1,2,4-triazol-3-yl)prop-2-yne (12.20 g). Recrystallisation from chloroform gave material m.p. 211 C. NMR (CDCl3): delta 4.45(2H,s), 7.1-7.3(15H,m), 7.95(1H,s).
