Reaction Steps

To a solution of 2-(4-isopropylpiperazin-1-yl)benzothiazole-6-carboxaldehyde (0.7 g, 2.42 mmol) and AcOH (291 mg, 4.84 mmol) in THF, dimethylamine hydrochloride (397 mg, 4.84 mmol) and NaCNBH3 (245 mg, 3.88 mmol) were added in turn. The reaction mixture was heated at 63° C. for 12 hours. The solvent was removed and the residue was extracted with ethyl acetate, washed with water and brine and dried (MgSO4). The volatiles were evaporated and the residue was purified by preparative HPLC to yield 250 mg (32%) of [2-(4-iso-propylpiperazin-1-yl)benzothiazol-6-ylmethyl]dimethylamine as a trifluoroacetate salt.
