Procedure
A 0.03M solution of 5-bromo-13-cyclohexyl-6,7-dihydro-5H-indolo[2,1-a][2]benzazepine-10-carboxylate (prepared as in Example 2) in MeCN was treated with (2-pyrrolidin-1-ylethyl)amine (5 eq) at 55° C. for 4 h; evaporation in vacuo to dryness gave crude methyl 13-cyclohexyl-5-[(2-pyrrolidin-1-ylethyl)amino]-6,7-dihydro-5H-indolo[2,1-a][2]benzazepine-10-carboxylate. Hydrolysis of the foregoing methyl ester was done with IM aqueous KOH (6 eq) in dioxane (0.1M) at 60° C.; the reaction was complete in 2 h, and the title compound was obtained in 24% yield after RP-HPLC purification and lyophilisation (Conditions: Column: Waters X-TERRA MS C18, 10 micron, 19×150 mm; Gradient: A: H2O+0.1% TFA; B: MeCN+0.1% TFA; 75% A isocratic for 3 min, linear to 20% A in 12 min).
