3-Chloro-methyl-6,7-dimethyl-1,2-benz-oxazole.

In the title compound, C(10)H(10)ClNO, the benzoisoxazole ring is almost planar (r.m.s. deviation = 0.0121 Å) and the chloro substituent in the side chain is anti-clinal relative to the N-C bond of the isoxazole ring. In the crystal, adjacent mol-ecules are linked via a pair of weak C-H⋯N hydrogen bonds, forming dimers through a cyclic R(2) (2)(8) association.

3-[Chloro-(phen-yl)meth-yl]-6-methyl-1,2-benzoxazole.

The title compound, C(15)H(12)ClNO, is a functionalized 1,2-benzoxazole with a chloro-(phen-yl)methyl substituent. The mol-ecule is V-shaped, the dihedral angle between the mean plane of the 1,2-benzoxazole system [maximum deviation = 0.023 (3) Šfor the N atom] and the phenyl ring being 70.33 (14)°. There are no hydrogen-bonding inter-actions in the crystal structure, which is stabilized by van der Waals inter-actions only.
