Procedure

A 10 mL microwave vial was charged with 12-chloro-4-[3-methyl-1-(propan-2-yl)-1H-1,2,4-triazol-5-yl]-9-oxa-3,6,13-triazatricyclo[8.4.0.02,6]tetradeca1(14), 2,4,10,12-Pentaene (160 mg, 0.470 mmol), toluene (4 mL), 1-methyl-4-(pyrrolidin-2-yl)piperidine (156 mg, 0.94 mmol), Pd(PtBu3)2(27 mg, 0.047 mmol), NaOtBu (135 mg, 1.40 mmol). The vial was sealed and degassed with N2 for three times. The resulting mixture was stirred at 110° C. for 1 h. After concentration, the residue was purified by reverse phase Combiflash eluting with a 0-50% gradient of CH3CN in 0.3% NH4HCO3 to give 249, which was separated by chiral HPLC (AD column, 30% EtOH (0.1% DEA) in n-hexane isocratic) to give: 9 mg of one enantiomer and 6 mg of the other (7% total yield)
