Procedure

38% aqueous formaldehyde (1.00 ml) and formic acid (1.00 ml) were added to 3-(2-fluoro-4-nitrophenoxymethyl)piperidine (compound of Reference Example 53; 0.300 g, 1.18 mmol), and the mixture was stirred at 90° C. for 1 hour. The reaction mixture was adjusted to pH=8 by addition of saturated aqueous sodium hydrogencarbonate, diluted with water, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate. The residue obtained by evaporation of the solvent under reduced pressure was purified by column chromatography on silica gel to give the title compound (0.275 g, 87%) as a yellow solid.
