6-(Piperazin-1-ylmethyl)-1,6,7,8-tetrahydro-3H-indeno[4,5-c]furan-3-one (40 mg, 0.15 mmol) and 4-methyl-5-oxiran-2-yl-2-benzofuran-1(3H)-one (55 mg, 0.29 mmol), were added to a 5 mL microwave tube containing a stir bar; to the mixture was added EtOH (2.5 mL). The tube was capped, degassed and purged with N2. It was then placed in a microwave reactor and heated at 150° C. for 30 min; LC indicated formation of the desired product. The solution was concentrated to dryness, dissolved in MeOH (3.5 mL), filtered and was then subjected to purification by mass-directed HPLC to give 6-({4-[2-hydroxy-2-(4-methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-yl}methyl)-1,6,7,8-tetrahydro-3H-indeno[4,5-c]furan-3-one. LC-MS (IE, m/z): 463 [M+1]+.
