Product 1

HCID 895258686-{3-Oxo-4-[2-(1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-yl}-5,6,7,8-tetrahydronaphthalene-2-carbonitrile

Procedure

The title compound was prepared from 1-[2-(1-Oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-2-one and 6-Oxo-5,6,7,8-tetrahydronaphthalene-2-carbonitrile following essentially the same procedure as Example 6. The product was purified by mass-directed reverse phase HPLC (AcCN-Water with 0.1% TFA). LC-MS (IE, m/z): 416 [M+1]+.
