Procedure

A solution of 160 mg (0.70 mMol) of 5-(2-amino-pyrimidin-4-yloxy)-1H-indole in 4 ml acetic acid is cooled to 10-15° C. Then 222 mg (3.5 mMol) NaBH3CN are added. After 1 h stirring at rt, 8 g of ice are added. Then the mixture is made basic by addition of 1 N NaOH and extracted three times with EtOAc. The organic layers are washed with water and brine, dried (Na2SO4) and concentrated at rt in vacuo: MS: [M+1]+=229.
