Procedure

Methanesulphonyl chloride (0.21 g, 1.85 mmole) was added dropwise to a solution of N-methyl-N-(3-methyl-5-aminobenzofur-2-ylmethyl)-4-methanesulphonamidophenethylamine (see Preparation 10B--0.78 g, 1.68 mmole) in pyridine (7 ml) and the solution was then stirred at room temperature for 60 hours. The solvent was evaporated and the residue triturated with toluene. The toluene was decanted, the residue stirred with aqueous sodium bicarbonate, and the precipitate collected by filtration and recrystallised from methanol to give the title compound, yield 0.38 g, m.p. 142°-143.5°.
