Versuchsvorschrift

N-[4-(2-{4-[(Aminooxy)methyl]phenyl}ethyl)-1,3-thiazol-2-yl]acetamide (30 mg) prepared in a similar manner according to Production Example 16, 37% formaldehyde (8 μl) and dry methanol (1 ml) were combined under nitrogen atmosphere. The reaction mixture was stirred at room temperature for 6 hours and concentrated in vacuo. The residue was purified by preparative silica gel column chromatography with chloroform/methanol (20:1) as an eluent, and triturated with ethyl ether to give N-{4-[2-(4-{[(methyleneamino)oxy]methyl}-phenyl)ethyl]-1,3-thiazol-2-yl}acetamide (20.9 mg) as a colorless solid.
