Procedure

A mixture of methyl 2-(7-bromo-4-hydroxy-1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxamido)acetate (400 mg, 1084 μmol), 3,5-dimethylisoxazol-4-ylboronic acid (305 mg, 2167 μmol) and Pd(PPh3)4 (125 mg, 108 μmol) in 8 ml 1,2-dimethoxyethane (or DMF) and 1.6 ml 2M aqueous Na2CO3 was heated to 75° C. and stirred for 12 hours. The mixture was cooled to 24° C., treated with 1M aqueous HCl and CHCl3, after which solids precipitated. The organic layer was separated and the solids were collected by filtration, and washed with MeOH.
