[Definition]

ChEBI: 2,4-dihydroxy-6-methylbenzoic acid ethyl ester is a 4-hydroxybenzoate ester.
[General Description]

Ethyl 2,4-dihydroxy-6-methylbenzoate is also referred as ethyl orsellinate. It was isolated from chloroform extract of Peltigera aphthosa. It is one of the product formed during alcoholyses of lecanoric acid.
[Synthesis]

The stem bark of Illicium difengpi (5.0?kg) was powdered and extracted three times with aqueous ethanol (ethanol/water 8:2) under reflux. The solvent was then evaporated under reduced pressure to obtain a dry residue (150?g). The residue was suspended in water (2?L) and extracted successively with petroleum ether (3 × 2?L), EtOAc (3 × 2?L) and BuOH (3 × 2?L), affording 5?g, 70?g, and 40?g, respectively, of each dried fraction. The EtOAc fraction was subjected to silica gel column chromatography using gradient elution (CH2Cl2/CH3OH, 200:1 to 2:1, v/v) to give four main fractions, of which was purified by successive silica gel column chromatography (CH2Cl2/CH3OH, 100:1→20:1); 2,4-dihy-droxy-6-methyl-benzoic acid ethyl ester (Ethyl 2,4-dihydroxy-6-methylbenzoate) was obtained from the fraction eluted by CH2Cl2/CH3OH (40:1)[1].

Store at -20°C
[Structure and conformation]

The mol-ecular structure of Ethyl 2,4-dihydroxy-6-methylbenzoate contains a methyl group, two hydroxyl groups, and a carboeth-oxy group, which are attached to C2, C4, C6 and C7 of the central benzene ring, respectively. An intra-molecular O3—H3···O1 hydrogen bond stabilizes the mol-ecular conformation. In the crystal, O4—H4···O3i and C3—H3A···O4ii hydrogen bonds link the mol-ecules into double strands parallel to the direction. In the solid state, the compound also forms offset slanted stacks of alternating inversion-related mol-ecules along the a-axis direction[1].
