실험 절차
To a 250 mL round bottom flask was added methanesulfonic acid (S)-2-oxo-pyrrolidin-3-yl ester (2) (4.76 mmol, 852 mg) and 5-methoxyspiro[indene-2,4′-piperidin]-1(3H)-one (3) (4.32 mmol, 1.00 g) in DIEA (17.29 mmol, 3.02 mL) and acetonitrile (20 mL). The solution was then heated to 85° C. for 90 min. The reaction was concentrated in vacuo and flash column chromatography (silica) was performed eluting with ethyl acetate to 20% MeOH/ethyl acetate afforded the title compound (1.05 g, 77% yield). Calculated MS=306.2. found MS (ESI) m/e 307.3 (M+H+); 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=2.253 min.
