Procedure

To a sealed tube charged with a magnetic stir bar was added (R or S)—N-((4-methoxy-6-methyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-2-methyl-1-(1-(piperidin-4-yl)ethyl)-1H-indole-3-carboxamide (Compound 326) (0.1 g, 0.229 mmol) was added DCM (3 mL) and the reaction cooled to 0° C. To the cooled reaction mixture was added oxirane which was condensed into the reaction vial (˜1 mL). The reaction was allowed to stir to rt over 4 h and was then conc. in vacuo to afford the crude material which was purified via silica gel chromatography (12 g) using ethyl acetate/MeOH (4:1) as eluent to afford the title compound as a white solid (50 mg).
