Reaction Steps

A mixture of the compound (100 mg) obtained in step (3) above, 4-fluorophenylboronic acid (66 mg), palladium(II) acetate (6.6 mg), tri(2-methylphenyl)phosphine (26 mg), potassium carbonate (186 mg), methanol (4.4 mL) and toluene (2.2 mL) was stirred in a sealed tube at 90° C. for 70 minutes. After being cooled to room temperature, the reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=99:1-0:100, then chloroform:methanol=100:0-85:15) to give methyl N-{[3-(4′-fluoro-4-biphenylyl)-7-hydroxy-2,3,6,8a-tetrahydro-5H-[1,3]oxazolo[3,2-a]pyridin-8-yl]carbonyl}-glycinate as a pale brown solid (100 mg).
