Методика

To a stirred solution of 4-propionylbenzenesulfonamide (prepared according to the procedure reported in Bioorganic Chemistry 1994, 22, 387-394), 2.2 g (10.3 mmol) in ethylacetate (20 ml) was added DMF (2.0 ml) followed by the addition of N,N-dimethylformamidedimethyl acetal (1.36 g, 1.51 ml, 11.36 mmol) in a dropwise manner at room temperature. The resulting mixture was stirred at room temperature for 4 hr. The progress of the reaction was monitored by TLC. The reaction mixture was concentrated under reduced pressure to obtain a solid product, which was washed with diisopropylether to obtain the title compound (2.6 g, 94%).
