<p>Novel pyrimidine derivatives represented by general formula (I): [wherein R1 is (I') (wherein R3 is a leaving group), hydroxycarbamoyl, or amino; and R2 is a group convertible into formyl]; and a process for the preparation of compounds represented by general formula (II) (wherein R4 is an amino-protecting group; and R2 is as defined above) by the use of the derivatives of general formula (I). The compounds of general formula (II) useful as intermediates for drugs can be prepared industrially and efficiently through novel intermediates represented by general formula (I).</p> |
