Participants

Reaction Steps

To a solution of 128 mg (0.215 mmol) of 4-{4-[(2S)-2-tert-butoxycarbonyl-2-(naphthalene-1-sulfonylamino)-ethylamino]-2-methyl-pyrrolo[2,3-d]pyrimidin-7-yl}-butyric acid ethyl ester (example 3b) in 1 ml of DMF was added 105 mg (1.05 mmol) of 1,4,5,6-tetrahydro-pyrimidin-2-ylamine and the reaction mixture was stirred at room temperature for 4.5 hours. The solvent was removed in vacuo and the residue was taken up in DCM and washed with a saturated NaCl solution. The organic phase was dried over MgSO4, filtered and the solvent was removed in vacuo. The residue was chromatographed on silica gel eluting with DCM/MeOH/AcOH/H2O (95:5:0.5:0.5). Yield: 72 mg.
