Reaction Steps

A solution of tent-butyl 2-(7-bromo-4-hydroxy-1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxamido)acetate (205 mg, 498 μmol), Pd2dba3.CHCl3 (52 mg, 50 μmol). X-Phos (48 mg, 100 μmol) and piperidine (123 μl, 1246 μmol) in 1,4-dioxane (5 ml) was treated with sodium tert-butoxide (192 mg, 1994 μmol). The reaction was stirred at 80° C. in a sealed tube. After 15 hours, the solution was cooled to 23° C., adsorped onto silica gel, concentrated in vacuo and purified by silica gel chromatography (eluant: 5% methanol/dichloromethane, followed by 5% methanol/dichloromethane+1% AcOH), affording an yellow solid which was 83% pure. The impure solid was purified by RP HPLC (0-100% MeCN/water+1% TFA, 10 min), affording 83 mg (46%) of the product as an yellow solid.
