Procedure

Suspend 132 mg (0.312 mmol) of (+/−)-cis-({3-[(6-phenylfuro[2,3-d]pyrimidin-4-yl)amino]cyclo-hexyl}oxy)acetic acid tert-butyl ester in 0.3 ml of tetrachloromethane, add 61 mg (0.343 mmol) of NBS and heat to reflux. On completion of conversion (approx. 1 h), cool the reaction mixture and isolate the product directly by preparative RP-HPLC. 104 mg (66.4% of theory) of the target compound are obtained.
