In a microwave tube was added 5-(5-amino-2-methylphenyl)-1-methyl-3-morpholinopyridin-2(1H)-one (1.0 equiv.), 5-bromo-1-ethyl-3-(trifluoromethyl)pyridin-2(1H)-one (2.0 equiv.), PdCl2(dppf).CH2Cl2 adduct (0.1 equiv.), Mo(CO)6 (1.0 equiv.), and THF (0.3 M). The mixture was capped and stirred while DBU (3.0 equiv.) was added, fizzing occurred and the tube was subsequently heated in the microwave at 150° C. for 15 min at which time LCMS indicated full conversion to product (M+H=517). The reaction was filtered, concentrated, and purified via preparative HPLC to yield 1-ethyl-N-(4-methyl-3-(1-methyl-5-morpholino-6-oxo-1,6-dihydropyridin-3-yl)phenyl)-6-oxo-5-(trifluoromethyl)-1,6-dihydropyridine-3-carboxamide (15% yield). 1H NMR (400 MHz, <cd3od>) δ ppm 1.42 (t, J=7.24 Hz, 3H) 2.30 (s, 3H) 3.08-3.21 (m, 4H) 3.64 (s, 3H) 3.80-3.92 (m, 4H) 4.16 (q, J=7.04 Hz, 2H) 6.93 (d, J=1.96 Hz, 1H) 7.28 (d, J=8.22 Hz, 1H) 7.34 (d, J=1.96 Hz, 1H) 7.47-7.60 (m, 2H) 8.48 (d, J=1.96 Hz, 1H) 8.70 (d, J=2.35 Hz, 1H). LCMS (m/z) (M+H)=517.1, Rt=0.81 min.
