Procedure

8-Hydroxymethyl-7-(2-methoxy-4-methoxymethoxyphenyl)-3,3-dimethyl-3,4-dihydro-1H-quinoxalin-2-one (Reference Compound No. 9, 495 mg, 1.33 mmol) was dissolved in anhydrous dichloromethane (10 mL), and triethylamine (250 μL, 1.80 mmol) and methanesulfonyl chloride (113 μL, 1.46 mmol) were added thereto successively. The reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled reference compound (239 mg) as a yellow amorphous product. (Yield 46%)
