Reaction Steps

To a 5 ml microwave tube were added 5-(bromoacetyl)-4,6-dimethyl-2-benzofuran-1(3H)-one (0.220 g, 0.777 mmol), 1-[(2R)-2-hydroxy-2-(4-methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-ium chloride (0.215 g, 0.777 mmol), and a stir bar; the mixture was dissolved in THF (2 mL). The tube was capped, degassed and purged with N2. The tube was then placed in an oil bath and heated at 50° C. for 12 h; LC indicated formation of the desired product. The solution was concentrated to dryness, dissolved in MeOH (3.6 mL), filtered and was then subjected to purification by mass-directed HPLC to give 5-({4-[(2R)-2-hydroxy-2-(4-methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-yl}acetyl)-4,6-dimethyl-2-benzofuran-1(3H)-one. LC-MS (IE, m/z): 479 [M+1]+.
