Participants

Reaction Steps

To a solution of 50 mg (0.125 mmol) of trans-7-(3-aminomethyl-cyclobutyl)-5-(3-benzyloxy-phenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine in 4 ml of dry acetonitrile is added at RT 16 μl (0.2 mmol) of ethyl isocyanate (Fluka, Buchs, Switzerland). After stirring for 16 h at RT, working-up is effected by partitioning between water and ethyl acetate. The organic layer is dried over magnesium sulfate and evaporated to dryness to provide trans-1-{3-[4-amino-5-(3-benzyloxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-yl]-cyclobutylmethyl}-3-ethyl-urea. Analytical HPLC: tR=6.77 min (Grad 2); ES-MS: m/eo=471.1.
