4-(4-Bromo-3-methyl-1H-pyrazol-1-yl)-6-(but-3-ynyloxy)pyrimidine
Abstract
There are two molecules in the asymmetric unit of the title compound, C12H11BrN4O. The dihedral angles between the pyrazole and pyrimidine rings are 1.28 (17) and 1.56 (17)° in the two molecules. In one of the molecules, the but-3-ynyloxy side chain is disordered over two sets of sites in a 0.714 (8):0.286 (8) ratio.
