C11 CO C13 08 ,02 new reports on the crystal structures of pyrimidine derivatives [2,3]. Recently we have reported the crystal structure of a pyrimidine derivative [4]. The molecule in the title crystal structure is stabilized by one intramolecular Ν-Η-Ό type of hydrogen bonding: <f(N3-H3N) = 0.90 Ä, d(H3N-06) = 1.97 Ä, d(N3· 06) = 2.706 Ä, ZN3-H3N-06 = 138°. The molecules in the unit cell are interlinked by van der Waals forces.
