Non-hydrogen atoms were refined anisotropically and hydrogen atoms were introduced. Final R is 0.073 for 1719 reflections. The assignment of N and O atoms in the oxazole ring was based on their thermal parameters, and is supported by the bond lengths of 1.276 (9) and 1.380 (9) Å for N=C and N-C, respectively.
