Procedure

tert-Butyl-(3-{2-[2-(3-chloro-4-hydroxy-phenyl)-ethylamino]pyrimidin-4-yl}-benzyl)-carbamic acid allyl ester (Intermediate 120, 168 mg) was dissolved in methylene chloride (5 mL), followed by addition of diisopropylethylamine (0.11 mL), 1,3-dimthylbarbituric acid (78 mg) then Pd(PPh3)4 (50 mg). The mixture was stirred at room temperature overnight. The mixture was washed with saturated NaHCO3, brine, dried over Na2SO4, filtered and chromatographed on silica gel with methyl chloride:methanol (95:5) to afford 120 mg of product in 86% yield. LC-MS showed the product had the expected M+H+ of 411. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.31 ppm) δ 8.3 (d, 1H) 8.1 (s, 1H) 8.0 (d, 1H) 7.5 (m, 2H) 7.2 (d, 1H) 7.1 (d, 1H) 7.0 (m, 1H) 6.8 (d, 1H) 3.9 (s, 2H) 3.7 (m, 2H) 2.8 (m, 2H) 1.3 (s, 9H).
