0.3 g of (5-amino-2-butyl-1-benzofuran-3-yl) {4-[3-(dibutylamino)-2-hydroxy-propoxy]-phenyl}methanone (III) was dissolved in 10 ml of dichloromethane. The solution was warmed to 30-35° C. and 0.06 g of pyridine was added at this temperature. After this 0.093 g of methanesulfonyl chloride was added and the mixture was stirred at 30-35° C. for 2 hours. The mixture was cooled to 20-25° C., washed with 2×15 ml of water, 2×15 ml of sodium hydrogencarbonate solution of 5%, 1×15 ml of water.
