1,4-Bis(1,1-dimethyl­prop­yl)-2,5-dimeth­oxy­benzene

The title compound, C(18)H(30)O(2), was prepared by Friedel–Crafts alkyl­ation of 1,4-dimeth­oxy­benzene with 2-methyl-2-butanol. The complete mol­ecule is generated by the application of a crystallographic centre of inversion. The two meth­oxy groups are oriented in the same plane of the aromatic ring [C—C—O—C torsion angle = 9.14 (16)°]. While one methyl group of the tert-pentyl substituent is coplanar with the benzene ring [C—C—C—C = 0.45 (15)°] and lies towards the less-hindered H atom, the other methyl and ethyl groups are directed to either side of the benzene ring [C—C—C—C torsion angles = 118.78 (12) and 59.11 (14)°, respectively]. In the crystal, the hydro­phobic mol­ecules pack to form a brick-wall-like architecture.
