Reaction Steps
To a solution of {3-[3-(2-chloro-3-trifluoromethyl-benzylamino)-propoxy]-phenyl}-acetic acid methyl ester (70 mg, 0.17 mmol) in dry dichloromethane (20 ml) was added acetic acid (2 drops) followed by 2-thiophen-3-yl-propionaldehyde (26 mg, 0.19 mmol) and sodium triacetoxyborohydride (72 mg, 0.34 mmol). After the resulting mixture was stirred at room temperature overnight, water was added to quench the reaction. The aqueous layer was extracted with ethyl acetate. The combined organic layers was washed with brine, dried over sodium sulfate and concentrated in vacco. The crude mixture was purified by HPLC (YMC CombiPrep ODS-A, 50×20 mm, 20 mL/min, A: acetonitrile B: water, A: 60 to 100% during 10 min, UV detection at 254 nm) to give 50 mg (32% yield) of the title compound as an oil MS m/e 541.4 (M+H)+.
