実験手順

A mixture of 16.0 g of 2-chloroacetyl-1-(o-fluorobenzyl)pyrrole, Example 1a, 8.3 g of di-sec-butylamine and 20.0 g of potassium carbonate in 250 ml xylene is stirred at 120° C. for 72 hours. The mixture is cooled, washed with water, dried and filtered and the xylene is evaporated leaving a brown oil. The oil is dissolved in ether and extracted into a 2N hydrogen chloride solution. The aqueous acidic solution is basified with a sodium carbonate solution and extracted with ether. The ether solution is washed, dried and filtered and the ether removed leaving a brown oil of 1-(o-fluorobenzyl)-2[(di-sec-butylamino)acetyl]pyrrole. Infrared and nuclear magnetic resonance spectra confirm this structure.
