反応手順

A solution of sodium hydroxide (1 g) in water (50 mL) was added to a solution of methyl 2-(2-fluorophenyl)-2-methylpropanoate (example 90, step b) (2.6 g) in methanol (50 mL) and THF (50 mL). The reaction mixture was heated at 40° C. for 40 hours. The organics were removed under reduced pressure and the remaining aqueous solution washed with ethyl acetate. The aqueous layer was cooled and acidified by addition of concentrated HCl. The mixture was extracted with ethyl acetate and the organic layer washed with brine before being dried over sodium sulphate, filtered and the solvent removed under reduced pressure to afford the subtitled compound. Yield 1.5 g.
