Reaction Steps

Under ice-cooling, pyridine (55 μL) and Methanesulfonyl chloride (35 μL) were added dropwise to a solution of [4-(4-fluorophenyl)-2,2,3-trimethyl-2H-chromen-7-yl]amine (a compound of Reference Example 6(5), 64 mg) in chloroform (3 mL), and the mixture was stirred at room temperature for 2 hours. The reaction mixture was purified by column chromatography on NH-silica gel (Chromatorex NH-silica gel, Solvent: chloroform/methanol=100/0 to 90/10) to give the titled compound (76 mg) as a colorless powder.
