2-(4-Fluoro-phenyl)-10-methanesulfonyl-5-methylene-5,6,7,8,9,10-hexahydro-1-oxa-7,10,11-triaza-cycloocta[f]indene-3-carboxylic acid methylamide (6.0 mg, 0.013 mmol) is dissolved in DCM (2 mL) and the solution is cooled to 0° C. Methanesulfonyl chloride (7.7 mg, 0.07 mmol) is added followed by triethylamine (6.83 mg, 0.07 mmol) and the reaction is allowed to warm up to RT over 3 h then evaporated to dryness and placed on the high vacuum overnight. The sample is then redissolved in EtOAc (25 mL) and then washed with 1N HCl (10 mL), then Brine (20 mL) and dried over Na2SO4. The organic is concentrated to afford 2-(4-Fluoro-phenyl)-7,10-bis-methanesulfonyl-5-methylene-5,6,7,8,9,10-hexahydro-1-oxa-7,10,11-triaza-cycloocta[f]indene-3-carboxylic acid methylamide (3 mg, 42%). MS-ES [M+H]+=523.0.
