Reaction Steps

To a solution of 2-(5-benzyloxycarbonylamino-6-oxo-2-phenyl-1,6-dihydro-1-pyrimidinyl)-N-(2-tert-butyldimethylsilyloxy-3,3,3-trifluoro-1-isopropylpropyl)acetamide (12.4 g) in tetrahydrofuran (100 mL) and ethanol (60 mL) was added 10% (w/w) palladium on carbon (1 g) and the suspension was placed under a hydrogen atmosphere (3.4 bar) and shaken for 12 h. The solution was filtered through diatomaceous earth to give an oil which crystallized from ether to provide 2-(5-amino-6-oxo-2-phenyl-1,6-dihydro-1-pyrimidinyl)-N-(2-tert-butyldimethylsilyloxy-3,3,3-trifluoro-1-isopropylpropyl)acetamide as a white solid (8.7 g); MS: m/z=513(M+1).
