• The free base has been used in the protection of OH groups as 2-quinolinylmethyl (Qm) ethers which can be cleaved by aerial oxidation in the presence of Cu(II): J. Org. Chem., 55, 5344 (1990), or by photolysis: Tetrahedron, 48, 10563 (1992). The protection of thiols has also been reported, as the Qm thioethers, which can be cleaved with Fe(III) or Cu(II): Chem. Lett., 803 (1993).

As with 2-(Chloromethyl)pyridine hydrochloride, A10226, lithiation of the free base can be effected at the methylene group. Quinolylaziridines are formed on subsequent reaction with imines: J. Org. Chem., 60, 2279 (1995).
