Procedure
Dimethyl-{4-[4-(3-thiomorpholin-4-ylpropoxy)phenyl]tetrahydro-pyran-4-ylmethyl}amine (300 mg, 0.792 mmol) and TFA (0.99 ml) were cooled to 0 to 5° C. and trifluoro-peracetic acid (4M, 0.77 ml) was added and the reaction allowed to warm to ambient temperature overnight. The mixture was diluted with DCM (6 ml), basified with NaOH (2M, 8 ml) and extracted with DCM (2×20 ml). The DCM extracts were dried over MgSO4, filtered and concentrated in vacuo at 35° C. Purification by chromatography on silica, eluant DCM:MeOH:NH3 (96:4:1) provided the title compound (151 mg, 46%) as a white solid. 1H NMR (400 MHz, CDCl3) δ7.22 (d, 2H), 6.85 (d, 2H), 4.01 (t, 2H), 3.75 (dt, 2H), 3.55 (td, 2H), 3.10-2.97 (m, 8H), 2.72 (t, 2H), 2.40 (s, 2H), 2.14-1.82 (m, 6H), 1.97 (s, 6H).
