Reaction Steps

The mixture of 3-(5-amino-2-methylphenyl)-1,7-dimethyl-1,6-naphthyridin-2(1H)-one 15 (165 mg, 0.589 mmol) and 1-cyclopropyl-3,3-bis(methylthio)prop-2-en-1-one 30 (111 mg, 0.589 mmol) in 1,4-dioxane (2 mL) was heated in a sealed vial at 150° C. overnight. The solvent was removed to yield crude (Z)-3-(5-(3-cyclopropyl-1-(methylthio)-3-oxoprop-1-enylamino)-2-methylphenyl)-1,7-dimethyl-1,6-naphthyridin-2(1H)-one 31 which was used without further purification. MS m/z 420.1 (M+1).
