Participants

Reaction Steps

50 mg (0.09 mmol) of trans-toluene-4-sulfonic acid 3-[4-amino-5-(3-benzyloxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-yl]-cyclobutylmethyl ester and 34 mg (0.225 mmol) of adamantan-1-ylamine (Fluka, Buchs, Switzerland) in 1 ml N,N-dimethylformamide are stirred for 18 h at RT and for 24 h at 60° C. Additional adamantan-1-ylamine is added (34 mg) and stirring is continued for 24 h at 120° C. The solvent is evaporated to dryness and the residue is purified by flash-chromatography (ethylacetate:methanol:NH4OHaqu.=95:5:1) to provide trans-7-[3-(adamantan-1-ylaminomethyl)cyclobutyl]-5-(3-benzyloxy-phenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine. Analytical HPLC: tR=11.14 min (Grad 1); ES-MS: m/eo=533.9.
