Reaction Steps

To a 10 mL microwave vial was added methanesulfonic acid (S)-2-oxo-pyrrolidin-3-yl ester (4.97 mmol, 890 mg) and (4-fluoro-phenyl)-piperidin-4-yl-methanone hydrochloride (4.97 mmol, 1.21 g) in DIEA (24.8 mmol, 5 mL) was heated to 85° C. for 105 min. The DIEA was decanted and flash column chromatography (silica) was performed eluting with ethyl acetate to 20% MeOH/ethyl acetate afforded the title compound (112 mg, 7.8% yield). MS (ESI) m/e 291.2 (M+H+), calculated 290.33; HPLC (Novapak 150×3.9 mm C18 column: mobile phase: 10-90% acetonitrile/water with 0.1% TFA, at 2 mL/min over 5 min.) retention time=2.303 min.
