実験手順
Dissolve 390.7 mg (1.17 mmol) of 4-chloro-5-(4-ethylphenyl)-6-phenylfuro[2,3-d]pyrimidine and 250 mg (1.17 mmol) of cis-(+/−)-{[(4-hydroxycyclopent-2-en-1-yl]oxy}acetic acid tert-butyl ester in 0.95 ml of DMF, cool to 0° C. and add 0.58 ml (1.17 mmol) of phosphazene base P2-t-Bu (2 M solution in THF). After the end of the addition, warm the mixture to RT and stir for a further 1 h. Then add the reaction mixture to water, adjust to pH 7 with 1N hydrochloric acid and extract three times with dichloromethane. Combine the organic phases, wash with satd. sodium chloride solution, dry over magnesium sulphate and concentrate under reduced pressure. Isolate the crude product by chromatography on silica gel (eluent: cyclohexane/ethyl acetate 20:1→5:1). 510 mg (85.3% of theory) of the target compound are obtained.
