Versuchsvorschrift

To a solution of 1-[N-trifluoroacetyl-N-[(4,5-diphenyloxazol-2-yl)methyl]amino]-2,3-dihydro-4-methoxy-1H-indene (0.29 g) of methanol (2 ml) was added 1N NaOH aqueous solution (2 ml). The mixture was refluxed for 1 day and the solvent was removed in vacuo. The residue was extracted with ethyl acetate, dried over MgSO4 and evaporated in vacuo. The residue was purified by chromatography on silica gel to afford 1-(4,5-diphenyloxazol-2-yl)methylamino-2,3-dihydro-4-methoxy-1H-indene (0.19 g). MS (m/z): 397 (M+ +1) NMR (CDCl3, δ): 1.85-2.10 (1H, m), 2.10 (1H, br), 2.33-2.52 (1H, m), 2.68-2.87 (1H, m), 2.92-3.12 (1H, m), 3.82 (3H, s), 4.14 (2H, s), 4.45 (1H, t, J=6.1 Hz), 6.74 (1H, d, J=7.9 Hz), 7.05 (1H, d, J=7.4 Hz), 7.20 (1H, dd, J=7.4, 7.9 Hz), 7.32-7.40 (6H, m), 7.57-7.67 (4H, m)
