Reaction Steps

100 mg (0.15 mmol) of tert-butyl 2-benzyloxycarbonylamino-3-{6-[6-(2,5-dimethyl-pyrrol-1-yl)-3′,4′,5′,6′-tetrahydro-2′H-[2.4′]bipyridinyl-1′-yl]-5-methyl-pyrimidin-4-ylamino}-propionate is dissolved in 3 ml of ethanol and 0.3 ml of water. 50 mg (0.75 mmol) of hydroxylamine hydrochloride is added and the reaction medium is heated for 18 hours at 90° C. The solvents are evaporated off under reduced pressure (2 kPa) and the crude residue is purified by chromatography on silica gel eluting with a CH2Cl2/MeOH mixture 90:10. 30 mg of expected product is obtained in the form of a resin.
