Embodiment 1
[0228] Example 1. Preparation of 3-[1-(2,4-dimethoxybenzyl)-2-oxo-2,5-dihydro-1H-pyrrol-3-yl]-N-hydroxyl propionamide ( 1e)
[0229]
[0230] Step 1. Preparation of Allyl-(2,4-Dimethoxybenzyl)amine (1b)
[0231] Under stirring, 0.32 ml of allyl bromide (3.66 mM) and 0.7 ml of diisopropylethylamine (3.99 mM) were added to 500 mg of 2,4-dimethoxybenzyl dissolved in dichloromethane In the reaction solution of amine (3.33 mM), the solution was left alone at room temperature. After neutralizing the reaction mixture with 10% NaOH solution, the mixture was extracted with chloroform, washed with saturated NaCl solution, washed with MgSO 4 Dry, filter, and concentrate in vacuo. The compound formed was purified by column chromatography on silica gel using a solvent mixture of methanol and chloroform (1:9) as eluent to give 276 mg of allyl-(2,4-dimethoxybenzyl)amine (1b) ( Yield: 40%).
