실험 절차
A mixture of the product of Example 208 in the form of its free base (2.0 g), 98% formic acid (8 ml) and 37-40% aqueous formaldehyde solution (25 ml) was stirred at room temperature for 2 hours. The mixture was then heated at 95°-100° C. for 18 hours, cooled, basified and extracted with ether. The extract was washed with water and dried. Dry hydrogen chloride gas was passed into the ethereal solution. Evaporation of the solvent gave a residue which was heated with ethyl acetate (20 ml) to give a white solid which was partitioned between ether and water. The aqueous phase was basified and then extracted with ether. The extract was dried and evaporated to give a residue which was distilled using a Buchi Kugelrohr apparatus (200° C./0.5 mm) to give N-methyl-N-(2-morpholinoethyl)-1-[1-(4-chlorophenyl)cyclobutyl]-2-methoxyethylamine.
