Methylhydrazine → HCID 66576808, compound

Participants

Reaction Steps

Compound 19 was synthesised following similar procedures outlined in Example 22 (Compound 9), using 3-methylbenzaldehyde 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 16 h in a sealed tube. Subsequently, the reaction mixture was partitioned between CH2Cl2 and water. The organic phase was separated using a phase separating cartridge and concentrated in vacuo. The crude residue was purified by column chromatography (silica gel, gradient 5 to 20% ethyl acetate/isohexane) yielding Compound 19 as a solid.
