The key intermediate, 6-methylazulene, was synthesized from readily available and inexpensive starting materials in 63% yield over two steps. The methylgroup of 6-methylazulene was then used as a synthetic handle to introduce different substituents at the 6-position via two different methods. Subsequently, the 1- and 3-positions were substituted with additional functional handles, such as formyl
