Versuchsvorschrift

To a solution of 4-(2-thiophenylsulfonyl)-1-(4-(2,2,2-trifluoro-1-hydroxy-1-methylethyl)phenyl)-2-piperazinecarbaldehyde (45 mg, 0.100 mmol) and morpholine (26.2 mg, 0.301 mmol, Aldrich, St. Louis, Mo.) in 1,2-dichloroethane (2.0 mL) was added sodium triacetoxyborohydride (106 mg, 0.502 mmol) and acetic acid (5.74 μL, 0.100 mmol). The reaction was stirred at room temperature for 1 h then quenched with methanol (5 mL) and concentrated. The crude material was dissolved in methanol, filtered and purified using prep HPLC (Phenomenex C18 column (150×30 mm) eluting with TFA in CH3CN/H2O (10% to 90% gradient over 25 min) at a 30 mL/min flow rate) to yield 1,1,1-trifluoro-2-(4-(2-(4-morpholinylmethyl)-4-(2-thiophenylsulfonyl)-1-piperazinyl)phenyl)-2-propanol (5 mg) as a mixture of four isomers.
