Reaction Steps

To a solution of 6-amino-5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (70 mg, 0.13 mmol) and Et3N (0.1 mL) in CH2Cl2 (2 mL) was added 3-chloropropane-1-sulfonyl chloride (140 mg, 0.92 mmol) dropwise at 0° C. The reaction mixture was stirred at 12° C. for 16 hours. The reaction mixture was concentrated to provide 6-(3-chloropropylsulfonamido)-5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (90 mg, yield: 100%), which was used directly in the next step without further purification.
