Procedure
(R)-8-Benzyloxy-5-oxiranylcarbostyril (100 mg, 0.34 mmol), prepared from literature procedure (Beeley, Lee James; Dean, David Kenneth, PCT Int. Appl. WO 9525104) and 4,7-dimethoxy-indan-2-ylamine (66 mg, 0.34 mmol), prepared from literature procedure (Sindelar, R. D.; Mott, J.; Barfknecht, C. F.; Arneric, S. P.; Flynn, J. R.; Long, J. P.; Bhatnagar, R. K. J. Med. Chem. (1982), 25(7), 858-64), are dissolved in toluene (1 mL). The reaction mixture was heated to 110° C. and the solvent is allowed to evaporate. The residue is then stirred at 110° C. for 4 hours. The reaction is shown to be complete by TLC. The product is purified by flash column chromatography (silica, dichloromethane/methanol 20:1). TLC (silica, dichloromethane/methanol 25:1 Rf=0.10). ES+ MS m/e 487 (MH+).
