실험 절차

Dissolve 500 mg (2.17 mmol) of (+/−)-cis-{[3-hydroxycyclohexyl]oxy}acetic acid tert-butyl ester in 2.0 ml of dry THF, cool to 0° C. and add 1.24 ml (approx. 2.5 mmol) of a 2N solution of phosphazene base P2-t-Bu in THF. After removing the cooling, stir the mixture at RT for a further 30 min, before adding 500.7 mg (2.17 mmol) of 4-chloro-5-phenylfuro[2,3-d]pyrimidine at RT. Stir the mixture at RT overnight and then concentrate under reduced pressure. Purify the residue by chromatography on silica gel (eluent: cyclohexane/ethyl acetate 10:1→8:1). The target product is obtained after further purification by means of RP-HPLC (eluent: acetonitrile/water). 380 mg (41.2% of theory) are isolated.
