実験手順

An amine linked to a resin is reacted with 2,3-dihydro-benzo[1,4]dioxine-5-carbaldehyde, thus giving C-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-methyleneamine. C-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-methyleneamine is derivatized with alkylation at the imino site, such as with methyl magnesium bromide. Other alkylating agents can be used according to the desired molecule. The resulting 1-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-ethylamine is cleaved from the resin. An example of a resin-cleaving agent is trifluoroacetic acid (TFA). The resulting 1-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-ethylamine can be used for synthesis of a compound of the embodiments. For instance, 1-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-ethylamine can be used to react with 4-(2-methanesulfinyl-benzooxazol-6-yloxy)-pyridine-2-carboxylic acid methylamide to form 4-{2-[1-(2,3-dihydro-benzo[1,4]dioxin-5-yl)-ethylamino]-benzooxazol-6-yloxy}-pyridine-2-carboxylic acid methylamide.
