实验步骤: 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.

实验步骤: A solution of Example 11A (0.150 g, 0.405 mmol) in dry dimethyl sulfoxide (1.3 mL) under a nitrogen atmosphere was treated with potassium carbonate (0.090 g, 0.648 mmol), and the bright yellow mixture was stirred at room temperature for 30 minutes. Then 3-chloropropane-1-sulfonamide (0.096 g, 0.607 mmol) and sodium iodide (0.091 g, 0.607 mmol) were added, and the resultant mixture was heated at 50° C. for 22 hours. Additional potassium carbonate (0.090 g, 0.648 mmol), 3-chloropropane-1-sulfonamide (0.096 g, 0.607 mmol) and sodium iodide (0.091 g, 0.607 mmol) were added and stirring was continued at 50° C. for 23 hours. The reaction was incomplete by LCMS, so additional potassium carbonate (0.090 g, 0.648 mmol), 3-chloropropane-1-sulfonamide (0.096 g, 0.607 mmol) and sodium iodide (0.091 g, 0.607 mmol) were added followed by continued stirring at 50° C. for 22 hours. The reaction mixture was cooled to room temperature, diluted with ethyl acetate (50 mL), and washed with water (3×25 mL) and brine (10 mL). The organic phase was dried over anhydrous MgSO4, filtered, and concentrated in vacuo. Purification by silica gel flash chromatography (10 g) eluting with 3% methanol/dichloromethane followed by trituration with diethyl ether (3×5 mL) afforded the title compound as white solid (0.128 g, 64%). MS (ESI+) m/z 509 (M+NH4)+, (ESI−) m/z 490 (M−H)−. stirring was continued at 50° C. for 23 hours were added by continued stirring at 50° C. for 22 hours The reaction mixture was cooled to room temperature washed with water (3×25 mL) and brine (10 mL) The organic phase was dried over anhydrous MgSO4 filtered concentrated in vacuo Purification by silica gel flash chromatography (10 g) eluting with 3% methanol/dichloromethane
