実験手順
The reaction mixture of 1-(2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-yl)cyclobutanecarbonitrile (0.32 g, 1.4 mmol) in N,N-dimethylformate (4.0 mL) and water (0.40 mL) was stirred at 100° C. for 2 h. After cooled to r.t., the mixture was diluted with water, adjusted to pH=2 with aqueous HCl, and extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure to afford the crude product which was directly used in next step reaction without further purification.
