A mixture of 2-aminomethyl-1-ethylpyrrolidine (0.34 ml; 0.00235 mole), anhydrous sodium carbonate (3.5 g) and chloroform (100 ml) was cooled on an ice bath and treated with 4-(7-trifluoromethyl-4-quinazolinylamino) benzene sulphonylchloride hydrochloride (1.0 g; 0.00235 mole) with vigorous sitrring. The mixture was stirred at ambient temperature for 4 hours and then filtered. The residue on evaporation of the solvent was triturated with ether and the resulting solid was filtered off, washed with a little ether and dried to give the quarter hydrate of the title compound (0.28 g), melting point 150°-152° C.
