実験手順
In a similar manner to that described in Reference example 3(g), a reaction was carried out using ethyl 2-butyl-3-[4-(2-hydroxyethoxy)phenyl]-2-methylpropionate (2.73 g), which is the product of Reference example 10(d), triethylamine (1.85 ml) and methanesulfonyl chloride (0.75 ml) and the reaction mixture was treated to afford the desired compound (3.17 g) as a syrup.
