Procedure

A mixture of A mixture of (2E)-3-{2-[(1-benzyl-3-pyrrolidinyl)amino]-4-methyl-5-pyrimidinyl}acrylic acid (693 mg), O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (264 mg), HOBt (290 mg) and EDCI (334 mg) in DMF (20 ml) was stirred at ambient temperature for 15 hours. The reaction mixture was poured into a mixture of AcOEt-H2O and the organic layer was washed with brine and dried over MgSO4. The solvent was evaporated in vacuo and the residue was chromatographed on silicagel eluting with AcOEt-MeOH (9:1). The eluted fractions containing the desired product were collected and evaporated in vacuo to give (2E)-3-{2-[(1-benzyl-3-pyrrolidinyl)amino]-4-methyl-5-pyrimidinyl}-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (200 mg).
