3-(4-[2-([10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-yl]-methyl-amino)-ethoxy]-phenyl)-2-ethoxypropanoic acid ethyl ester (example 10)(1.5 g, 3.07 mmol) was dissolved in ethanol (20 ml) and 20% sodium hydroxide (2 ml) was added. After 6 days ethanol was evaporated in vacuo, water (50 ml) and acetic acid (2 ml) were added and the mixture was extracted with dichloromethane. The organic phase was dried (MgSO4) and the solvent evaporated in vacuo. The residue (1.4 g) was dissolved in acetone and neutralized with solution of hydrogen chloride in diethyl ether. The solvents were evaporated and the residue was triturated with diethyl ether yielding 1.15 g (74%) of the title compound as amorphous solid (hemihydrate). 1H NMR (250 MHz, DMSO-d6) δ10.50 (bs, 1H); 7.60 (bs)+7.10-7.50 (m, 10 H), 6.87 (d, J=7.9 Hz, 2H), 5.84 (bd, J=7.0 Hz, 1H), 4.49 (bs, 2H), 4.00 (t, J=5.6 Hz; +bm, 3H), 3.30-3,60 (m+m, 4H), 2.80-3.10 (s+bm, 7H), 1.07 (t, J=7.2 Hz, 3H).
