合成路线1
该中间体在本合成路线中的序号:(XVII)Carboxylic acid (XV) was coupled with cyclopentylamine (XVI) using EDC and HOBt to produce amide (XVII), which was cyclized to the fused pyrazinone derivative (XVIII) by treatment with pyridinium p-toluenesulfonate in toluene. The benzyloxycarbonyl group of (XVIII) was then removed by catalytic hydrogenation to give amine (XIX). This was finally coupled with (3,4,5-trimethoxyphenyl)glyoxylic acid (XX) to yield the title amide.
