0.189 g of (E)-3-(1-phenylmethanesulfonyl-1H-pyrrol-3-yl)-N-(tetrahydropyran-2-yloxy)-acrylamide (compound A2) are dissolved in 50 ml of a methanol/water (3/2) solution. Then 0.102 g of the acidic ion exchange resin amberlyst IR15 are added and the mixture is stirred for 91 hours at ambient temperature. The mixture is filtered. The filtrate is evaporated.
