Procedure

Compound 43 was synthesised following similar procedures outlined in Example 22 (Compound 9), using 4-iodobenzaldehyde instead of benzaldehyde in Step 1 and methyl hydrazine instead of hydrazine hydrate in Step 3. As a slightly modified procedure, Step 3 was performed at 60° C. for 4 h in a sealed tube. Subsequently, the mixture was cooled and filtered, and the residue was washed with cold ethanol. The filtered residue was purified by column chromatography (silica gel, gradient 5 to 10% ethyl acetate/isohexane) yielding Compound 43 as an off-white solid.
