Reaction Steps

To 19.6 g (44.9 mmol) 4-(6-Iodo-1-methyl-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-ylmethyl)-benzoic acid methyl ester and 23.2 g (179.6 mmol) di-isopropyl ethylamine in 200 ml DMF is added bis-triphenylphosphine palladium di-chloride (1.0 g, catalytic) followed by CuI (0.4 g, catalytic). 7.3 g (62.9 mmol) 3-phenyl-propyne is added and the mixture is heated to 70° C. for 6 hrs. The mixture is allowed to cool to room temperature and stir overnight. Water is added and the mixture stirred 30 minutes. Filter and dry under reduced pressure. Solid from EtOAc.
