Procedure

A solution of C-[4-(4-nitro-phenyl)-tetrahydro-pyran-4-yl]-methylamine (as prepared in Example 73, step (b)) in DCM is treated with formaldehyde according to the literature procedure found in J. Org. Chem., 61, 3849-3862, (1996). The mixture is diluted with EtOAc and washed with water. The organic layer is dried (MgSO4) and concentrated in vacuo. The residue is purified by silica gel chromatography with the appropriate solvent to afford the title compound.
