Reaktionsschritte
To a 25° C. mixture of 20.0 g (0.112 mol) of 6-methoxy-4-chromanone and 18.09 g (0.169 mol) of 3-pyridinecarbaldehyde in 100 ml of methanol was added 14.1 ml (0.169 mol) of pyrrolidine. The resultant solution was allowed to stir 60 hours at 25° C., cooled to 0° C. and filtered to yield 17.07 g (57%) of the title compound, m.p. 127°-131° C.
