Reaction Steps

To tert-butyl (3R)-3-[{[4-(2-aminoethyl)-2,2,7-trimethyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-6-yl]carbonyl}(isopropyl)amino]piperidine-1-carboxylate (200 mg) were added triethyl-amine (0.040 ml), tetrahydrofuran (3 ml), acetyl chloride (0.04 ml) under ice-cooling, and the mixture was stirred at room temperature for one hour. After the reaction was complete, the mixture was concentrated, and the obtained residue was purified by silica gel column chromatography (chloroform/methanol=9/1) to give the title compound (80 mg) as colorless amorphous.
