実験手順

In a dry flask under nitrogen was placed 1.20 gram of 2-(azetidin-1-ylsulfonyl)benzenesulfonamide, 50 ml of dry dichloromethane and 2.48 ml of 2M trimethylaluminum in toluene. To this was added 0.885 g of 4,6-dimethoxy-1,3,5-triazin-2-ylcarbamic acid methyl ester and the resultant solution was heated to reflux for 12 hours. The solution was washed with 50 ml of a water/acetic acid/1N HCl solution (40:10:0.4). The organic fraction was concentrated and chromatographed on silica gel (ethyl acetate/methylene chloride (15:85)). The slower moving portions were collected, treated with ethyl acetate and dried to give 0.45 g of a solid, m.p. 175°-177° C.
