Reaction Steps

This mixture was diluted with 30 mL MeOH and ran through an H-cube hydrogenator (1 mL/min, 60 bar, 70 deg C.) to provide, after concentration, methyl 2-(2,6-difluoro-4-(tetrahydrofuran-3-yl)phenyl)thiazole-4-carboxylate (44 mg). This ester was diluted with THF (3 mL) and water (1.5 mL) and LiOH (6.5 mg, 2.0 equiv.) was added. After stirring for 2.5 hours at rt, the mixture was neutralized with 1 N HCl(aq), diluted with EtOAc and washed with brine. The organic extracts were dried (Na2SO4) and concentrated in vacuo to provide the title compound (42 mg, quant).
