Procedure: A mixture of 129.0 g of di-sec.-butylamine and 129.0 g of chlorobenzene was reacted with phosgene in accordance with Example 1. When the phosgenation was complete, the mixture was heated under reflux for a further hour, the residual phosgene was then removed by blowing out with nitrogen, and, after the solvent had been removed under a moderate vacuum, the main product was collected by distillation. N,N-di-sec.-butylcarbamoyl chloride was obtained in this manner in a yield of 186.0 g and in a purity of 99.8%. The yield of 100% strength carbamoyl chloride was 185.6 g, corresponding to 96.9% of theory. A residue of 2.5 g (corresponding to 1.2% of the theoretical yield) remained in the distillation flask. the mixture was heated under reflux for a further hour the residual phosgene was then removed after the solvent had been removed under a moderate vacuum the main product was collected by distillation

Procedure: 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. The mixture is cooled washed with water dried filtered the xylene is evaporated leaving a brown oil extracted into a 2N hydrogen chloride solution extracted with ether The ether solution is washed dried filtered the ether removed
