Reaction Steps

A mixture of 2-chloro-6-methyl-3-pyridinylamine (8.5 g) and diethyl ethoxymethylenemalonate (22.0 mL) is heated at 140° C. for 18 hours. The mixture is cooled to room temperature and the resulting solids are recrystallized from a mixture of heptane (400 mL) and CH2Cl2 (2 mL) to obtain 17.9 g (95%) of the title compound as a pale red solid. Physical characteristics: MS (ESI+) m/z 313 (M+H).
