Reaction Steps

Suspend 100 mg (0.236 mmol) of (+/−)-cis-({3-[(5-phenylfuro[2,3-d]pyrimidin-4-yl)oxy]cyclohexyl}oxy)acetic acid tert-butyl ester in 0.2 ml of tetrachloromethane and add 46.1 mg (0.259 mmol) of NBS. Stir the reaction mixture at 60° C. for a total of 2 h, and add a further 23 mg of NBS after 1 h. After cooling, remove the tetrachloromethane under reduced pressure and purify the residue by preparative RP-HPLC (eluent: acetonitrile/water). 43.6 mg (36.8% of theory) of the target product are obtained.
