Procedure: To a solution of N-(4-chloro-phenyl)-ethane-1,2-diamine (0.68 g, 3.96 mmol) in isopropanol (8.0 mL) was added 2,6-lutidine (0.31 mL, 2.64 mmol) and catalytic potassium iodide. This mixture was heated to 80° C. and then treated with 2-[5-(3-bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.15 g, 0.4 mmol) in portions over 2 h. The solution was then stirred at 80° C. for an additional 18 h. The reaction mixture was concentrated in vacuo, then purified by flash chromatography on silica gel (gradient elution from 95% ethyl acetate/5% methanol to 90% ethyl acetate/20% methanol) to yield the title compound. 1H-NMR (DMSO) δ: 1.40 (6H, s), 2.20-2.40 (2H, m), 2.70-2.90 (3H, m), 3.10-3.30 (3H, m), 5.20 (2H, br, s), 5.80 (1H, m), 6.15 (1H, t), 6.60-6.70 (1H, m), 7.10-7.30 (4H, m) 7.50 (2H, m), 7.80 (1H, dd), 8.50 (1H, dd). ESI-MS m/z: 464 (M+1), UV retention time: 1.40 min. The reaction mixture was concentrated in vacuo purified by flash chromatography on silica gel (gradient elution from 95% ethyl acetate/5% methanol to 90% ethyl acetate/20% methanol)

Procedure: The hydrochloride salt of 4-chloroaniline (6.2 g, 38 mmol) and 2-oxazolidone (3.29 g, 38 mmol) was suspended in a minimal amount of di(ethyleneglycol)methyl ether amd the resulting suspension heated at 160° C. After 4 h CO2 evolution ceased and the reaction mixture was cooled to ambient temperature. The resulting solid was crystallized from EtOH/ether to yield 4.6 g (58%) of 4-chloroanilinoethylamine as its HCl salt. MS CI (M+H)+ at m/z 171. The free amine was prepared by partitioning the HCl salt between CH2Cl2 and NaHCO3 (sat.), drying the organic layer (Na2SO4), filtering and concentrating. the reaction mixture was cooled to ambient temperature The resulting solid was crystallized from EtOH/ether
