Versuchsvorschrift

The dried resin to which the C-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-methyleneamine (1 eq) was bound was suspended in dry toluene. Under a nitrogen atmosphere methyl magnesium bromide (150 eq) in a 3 M solution in ethyl ether was added. This mixture was shaken for 24 hours at 60° C. then filtered and washed with toluene, water, then methanol and dichloromethane alternately three times. The final wash was with methanol. The solid was dried under vacuum.
