Reaction Conditions

Temperature140 °C

Reaction Steps

A mixture of 6-methyl-5-(oxiran-2-yl)-2-benzofuran-1 (3H)-one (22 mg, 0.12 mmol) and 6-(2-Oxopiperazin-1-yl)-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (30 mg, 0.12 mmol) in EtOH (2 mL) was heated to 140° C. for 1 hour. The reaction mixture was concentrated to dryness, and dissolved in MeOH, filtered and shot into Mass-directed HPLC for separation to give the title product. LC-MS (IE, m/z): 446 [M+1]+.
