Procedure

To a stirred solution of anisole (0.40 mL, 3.68 mmol) in dry toluene (2.00 mL) was added titanium tetrachloride (0.24 mL, 2.18 mmol) at room temperature under argon. The mixture was then treated with 1-piperonylpiperazine (2.07 g, 9.40 mmol) and 4-chloro-11-oxo-10,11-dihydro-5H-dibenzo[b,e][1,4]diazepine (0.49 g, 2.00 mmol) (Giani et al, supra) and diluted with toluene (1.00 mL). After more 1-piperonylpiperazine (1.19 g, 5.40 mmol) was added, toluene (8.00 mL) was added and the resulted reaction mixture was heated at reflux for 6 h before it was cooled to 60° C. Isopropanol (0.80 mL), celite (0.40 g) and ammonia (30%, 0.50 mL) were added sequentially and the whole mixture was filtered hot. Upon cooling to room temperature, the filtrate was concentrated in vacuo to dryness and the residue was subjected to column chromatography using ethyl acetate/hexanes (1/2) as the eluent. Thus 0.63 g (70%) of the title compound was afforded as a light yellow solid; m.p. 160-162° C.; MS 447 (M+ +1).
