N-[4-({4-[(dimethylphosphoryl)methyl]piperazin-1-yl}methyl)-3-(trifluoromethyl)phenyl]-3-ethynyl-4-methylbenzamide (0.22 mmol), 7-bromo-4H-Pyrido[3,2-b][1,4]oxazin-3-one (45.8 mg, 0.2 mmol), Pd[(PPh3)]4 (11.6 mg, 0.01 mmol), CuI (2.9 mg, 0.015 mmol) is placed in a vial capped with rubber septa. This vial is subjected to 3 cycles of vacuum-refilling with N2. To this mixture is added anhydrous N,N-diisopropylethylamine (0.1 mL, 0.6 mmol) and DMF (1.0 mL). The resulting solution is stirred at 80° C. for 24 h. After the reaction mixture is cooled, water and EtOAc are added to facilitate the extraction. The combined organic layers are dried over Na2SO4, filtered, and then concentrated on a rotavap and the residue is purified on a silica gel column (eluent: 10% MeOH in CH2Cl2, MeOH is pre-saturated with NH3 gas).
