2-Chloro-3-hydroxymethyl-6-methoxyquinoline

F. N. Khan, S. Mohana Roopan, V. R. Hathwar and S. W. Ng

All the non-H atoms of the title compound, C₁₁H₁₀ClNO₂, are roughly coplanar (r.m.s. deviation = 0.058 Å). In the crystal, adjacent molecules are linked by an O—H

N hydrogen bond, generating chains running along the a axis.

Substituted quinoline-3-carbaldehydes are intermediates for annelation and functional group modification; for a review of the synthesis of quinolines by the Vilsmeier–Haack reaction, see: Meth-Cohn (1993).

Experimental top

2-Chloro-8-methoxyquinoline-3-carbaldehyde (220 mg, 1 mmol), sodium borohydride (38 mg, 1 mmol) and a catalytic amount of montmorillonite K-10 were placed in a beaker. The contents were irradiated at 500 W for 5 min. The product was dissolved in ethyl acetate and the residue removed by filtration. The filtrate was subjected to column chromatography on silica, and ethyl acetate/petroleum ether was used as the eluant. The solvent was evaporated and the residue recrystallized from chloroform to give colorless crystals.
