合成路线图解说明:

The acidic hydrolysis of 3-nitro-4-hydroxyphenyl-alpha-methylacetonitrile (I) gives 3-nitro-4-hydroxyphenyl-alpha-methylacetic acid (II), which is converted to 3-amino 4-hydroxyphenyl-alpha-methylacetic acid (III) by catalytic hydrogenation. The condensation of (III) with 4-fluorobenzoyl chloride yields 3-(4-fluoro benzamido)-4-hydroxyphenyl-alpha-methylacetic acid (IV), which is cyclized in acidic medium to give 2-(4-fluorophenyl)-alpha-methyl-5-benzoxazoleacetic acid (V). The racemic (V) was optically resolved by N-methyl-D-glucamine, yielding S-(+)-2-(4-fluorophenyl)-alpha-methyl-5-benzoxazoleacetic acid.
