合成路线1
该中间体在本合成路线中的序号:(I)The reaction of (I) with acetonitrile in sulfuric acid provides the amide (II), which after hydrolysis in 12N HCl/methanol yields the 4-amino derivative (III). Acylation of (III) with isobutyryl chloride followed by reduction with borane-methylsulfide complex gives the racemate (V), MK-927 (2). The resolution of MK-927 is accomplished through the di-p-toluoyl-D-tartaric acid salt.
