5-Fluoro-1-(piperazin-1-ylmethyl)-2,3-dihydro-1H-indene-4-carbonitrile (60 mg, 0.23 mmol), 4-methyl-5-oxiran-2-yl-2-benzofuran-1(3H)-one (88 mg, 0.46 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 120° C. for 1 hour; LC indicated formation of some desired product. The tube was again placed in a microwave reactor and heated again at 150° C. for 30 min; LC indicated formation of more product. The solution was concentrated to dryness, re-dissolved in DCM (20 mL) and was then absorbed into silica gel. It was then loaded onto a silica column for separation with the solvent system of (10% MeOH in DCM), to give 5-fluoro-1-({4-[2-hydroxy-2-(4-methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-yl}methyl)-2,3-dihydro-1H-indene-4-carbonitrile. LC-MS (IE, m/z): 450 [M+1]+.
