Reaction Steps
A sealed tube containing 1-[2-(4-Methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-2-one (60 mg, 0.19 mmol) and 4-methyl-5-[(2R)-oxiran-2-yl]-2-benzofuran-1(3H)-one dissolved in 1 mL of EtOH was heated to 100° C. overnight. After 16 hrs the solvent was removed and the material purified via flash chromatography to give the title product. LC-MS (IE, m/z): 465 [M+1]+.
