Then 2-dimethylaminoethyl chloride hydrochloride (0.29 g) was added and the solution was heated at 100° C. under stirring for 6 hours. The reaction mixture was cooled, then poured into water, and the separated oil was extracted with ethyl acetate. The organic layer was dried, then evaporated to dryness to give 500 mg of the title compound as a crude residue, which was purified through its hydrochloride salt. This was obtained by dissolving the free base in acetone, adding a hydrochloric acid ethereal solution and filtering off the crystallized salt.
