実験手順
(O'Reilly, N. J., Derwin, W. S., Fertel, L. B., Lin, H. C., Synlett., (1990) 609-610.) A solution of 2-(dipropylamino)-2,3-dihydro-1H-indene-5,6-dicarboxylate (92, 0.35 g, 1.0 mmol) and 4-fluorobenzylamine (0.15 mL, 1.3 mmol) in glacial HOAc (30 mL) was refluxed at 113° C. After 4 h, the reaction was cooled to r.t., concentrated, then azeotroped with toluene. The residue was diluted with water and basified with sat'd Na2CO3 (or sat'd NaHCO3) to pH>12. The solution was extracted with CH2Cl2 and the organic layers were washed with brine, dried (MgSO4), and concentrated. The residue was purified by using silica gel, eluting with 4:1 CH2Cl2/acetone+0.1 % MeOH, to give 101 as a light yellow oil that was converted to an HCl salt and recrystallized from MeOH/EtOAc to give a white solid (m.p. 251-253° C.).
