Procedure
To a solution of 0.095 g (0.23 mMol) 4-chloromethyl-N-(7-cyclohexyl-4-methoxy-benzothiazol-2-yl)-benzamide in 1 ml THF were added 0.16 g (1.83 mMol) N-(2-methoxyethyl)-methyl amine. The reaction mixture was heated to 70° C. for 2 h. The solvent was evaporated to dryness, the residue taken up in ethyl acetate and washed with water and brine. The organic phase was dried over sodium sulfate and evaporated to dryness in vacuo. The residue was subjected to column chromatography (dichloro methane/methanol 19:1) to yield (0.087 g (81%) of N-(7-cyclohexyl-4-methoxy-benzothiazol-2-yl)-4-{[(2-methoxy-ethyl)-methyl-amino]-methyl}-benzamide as a light yellow foam. ES-MS m/e (%): 468 ([M+H]+, 100).
