Procedure: 14 g of ethyl acrylate in 45 ml of ethanol are added dropwise to 23.8 of the amine obtained in Stage C of Example 1 dissolved in 45 ml of ethanol. The mixture is stirred at room temperature for 3 hours, evaporated, and the residual oil is distilled in a Kugelrohr (bulb tube) at 120° C. and 0.09 mm Hg. evaporated the residual oil is distilled in a Kugelrohr (bulb tube) at 120° C.

Procedure: 7.4 g of the compound obtained in Stage C of Example 1 are dissolved in 10 ml of ethanol, then 4.73 ml of ethyl acrylate dissolved in 12 ml of ethanol are poured onto the solution. The mixture is left at room temperature for one night, and then concentrated in a rotary evaporator and distilled in a Kugelrohr to yield the compound in the form of an oil. are poured onto the solution The mixture is left at room temperature for one night concentrated in a rotary evaporator distilled in a Kugelrohr to yield the compound in the form of an oil
