The resulting mixture was heated under argon at 90° C. with stirring for 2 days. The mixture was then cooled, diluted with dichloromethane (5 mL), dried with sodium sulfate and concentrated under reduced pressure. Flash chromatography (ISCO system, silica, 0-50% ethyl acetate in hexane) provided 126 as an impure oil: LRESIMS m/z 241.1 [M+H]+, calcd. for C15H17N2O1 241.1.
