Procedure
2-(2-Nitro-5-piperazinylphenyl)-1,3-dioxolane (6.63 g, 24 mmol) was added portionwise over 1 hour to a stirred solution of 3,4-dimethoxybenzoyl chloride (4.76 g, 24 mmol) and pyridine (4.04 g, 48 mmol) in dry dichloromethane (200 mL). The mixture was stirred overnight at room temperature, washed twice with water and concentrated in vacuo to provide 2-[2-nitro-5-[4-(3,4-dimethoxybenzoyl)piperazinyl]phenyl]-1,3-dioxolane used without further purification below.
Workup
- washwashed twice with water
- concentrationconcentrated in vacuo
