Procedure
To a solution of tert-butyl (3R)-3-[{[4-(2-{benzyl[(benzyloxy)carbonyl]amino}ethyl)-2-(hydroxymethyl)-2-methyl-3-oxo-7-(trifluoromethyl)-3,4-dihydro-2H-1,4-benzoxazin-6-yl]carbonyl}-(isopropyl)amino]piperidine-1-carboxylate (700 mg) and triethylamine (0.25 ml) in tetrahydrofuran (8 ml) was added dropwise methanesulfonyl chloride (0.11 ml), and the mixture was stirred at room temperature for 2 hours. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous sodium chloride solution, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (793 mg).
