Reaction Steps

Triethylamine (0.08 mL) was added to a suspension of the product of Example 292, 4-{[4-(2-butynyloxy)phenyl]sulfonyl}-N-hydroxy-1,4-diazepane-5-carboxamide (0.10 g), in methanol (6 mL) to give a solution which was cooled to 0° C. lodomethane (0.025 mL) was then added. After 30 min the reaction mixture was allowed to warm to 25 ° C. After 20 min additional iodomethane (0.02 mL) was added followed by additional triethylamine (0.015 mL). After 18hours the reaction mixture was diluted with dichloromethane and water. The aqueous phase was washed with dichloromethane (3×). The combined organic extracts were dried over anhydrous sodium sulfate and concentrated in vacuo. The material obtained was combined with material from a previous reaction run on the same scale and chromatographed on silica gel to give 4-{[4-(2-butynyloxy)phenyl]sulfonyl}-N-hydroxy-1-methyl-1,4-diazepane-5-carboxamide (0.067 g). Electrospray Mass Spec 382.2 (N+H)+
