Combine 2-methyl-5H-dibenzo[b,e][1,4]diazepin-11-ylamine hydrochloride (600.0 mg, 2.31 mmol), (S)-2-phenethyl-piperazine (879.1 mg, 4.62 mmol), N,N-diisopropylethylamine (298.6 mg, 2.31 mmol), DMSO (1.0 ml), and toluene (4.0 ml). Stir and heat the mixture at 110° C. After 67 hours, cool the mixture to ambient temperature and then dilute it with ethyl acetate. Wash the organic layer with 0.1 N NaOH and brine. Dry (sodium sulfate) and concentrate the organic layer to residue. Purify the residue on silica gel using dichloromethane/methanol (90:10) to give 646.3 mg (71%) of a tan foam: mp 67°, dec; mass spectrum (ion spray): m/z=397.3 (M+1).
