Reaction Steps

3-chloropropane-1-sulfonamide (1.8 eq), DMAP (2.9 eq) and EDC (1.8 eq), were added to a solution of (7R)-7-[{2-[(tert-butoxycarbonyl)amino]ethyl}(methyl)amino]-14-cyclohexyl-7,8-dihydro-6H-indolo[1,2-e][1,5]benzoxazocine-11-carboxylic acid (prepared as described in Example 1, Step 7) (0.025 M) in DCM. The reaction was stirred under N2 at 40° C. for 2 h, before being allowed to cool. Volatiles were removed in vacuo to leave the crude product as a yellow gum which could be taken on without further purification. (ES+) m/z 687 (M+H)+; 689 (M+H)+
