Procedure

Reaction of methyl ether (267) (35 mg, 0.06 mmol) prepared as described in example 224 according to the proceedure described in example 81, except that the reaction mixture was diluted with saturated sodium bicarbonate and extracted with ethyl acetate. The organic phase was dried, the drying agent was removed and the solution was concentrated to dryness. Chromatography on silica eluting with methanol/dichloromethane (1:9 to 1:3), gave acylsulfonamide (271) (8 mg, 23%) as an orange powder, mp 229–233° C. 1H NMR δ [(CD3)2SO] 11.05 (br s, 1H), 9.37 (br s, 1H), 8.37 (d, J=2.5 Hz, 1H), 7.74 (s, 1H), 7.61–7.52 (m, 3H), 7.50–7.43 (m, 2H), 7.14 (dd, J=8.7, 2.5 Hz, 1H), 4.63 (m, 2H), 3.21 (partially obscured m, 2H), 2.81 (m, 2H), 2.59 (t, J=6.8 Hz, 2H), 2.38 (s, 6H). FABMS found [M+H]+: 569.1255, 571.1204. C27H25ClN4O6S requires 569.1262, 571.1232.
