How is 5-Methoxy-4-methyl-3-pyridinamine (CAS: 77903-28-7) typically synthesized?

5-Methoxy-4-methyl-3-pyridinamine is typically synthesized from 4-methyl-3-pyridinone via the methylation of the nitrogen atom followed by the introduction of the methoxy group. The synthesis involves the use of methyl iodide as a methylating agent and potassium carbonate as a base. This method provides good selectivity and yield, with the final product being purified by recrystallization.
