Reaction Steps

A mixture of 0.70 g (1.5 mmol) of 5-amino-2-[[4-[3-(tert-butoxycarbonylamino)pyrrolidin-1-yl]phenyl]amino]-4-(cyclopentylamino)-pyrimidine, 0.52 g (4 mmol) of butyl glyoxylate (F. J. Wolf, J. Weijlard, Org. Synth. Coll., 1963;4:124–125) and 0.5 mL HOAc in 15 mL of EtOH is heated under reflux for 14 hours, and the solvent is removed under vacuum. The residue is diluted with aqueous ammonia solution and extracted into EtOAc. Chromatography on silica, eluting with hexane/EtOAc (3:2), gives 0.21 g (28%) of the title compound (Compound 53): mp (MeOH) 226–228° C.
