Procedure
Helioxanthin (1.0 g) was suspended in benzene (10 ml), followed by addition of methylamine (40% methanol solution: 2 ml). The mixture was heated at 120° C. under stirring for 4 days. The reaction mixture was concentrated under reduced pressure. The resulting residue was recrystalized from DMF to yield the title compound (144 mg).
