Reaction Conditions

Reaction Steps

A solution of methylamine in methanol (40%, 5.0 ml) was added to a solution of ethyl 2-butyl-3-[4-(3-methansulfonyloxypropoxy)phenyl]propionate (500 mg), which is the product of Reference example 21 (c) in toluene (10 ml). The mixture was stirred at 90° C. for 2 days. The reaction mixture was concentrated under reduced pressure. The residue was partitioned between ethyl acetate and water and the layers were separated. The ethyl acetate solution was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified via chromatography on a silica gel column using dichloromethane/methanol=5/1 as the eluant to afford the title compound (389 mg) as a pale yellow oil.
