Procedure
To a stirred solution of t-butyl hydroquinone (1.0 Kg) in 2-methoxy ethanol (2.0 L), was charged K2CO3 (2.0 Kg) portionwise under nitrogen atmosphere and the mixture refluxed. Benzyl chloride (0.762 L) was added dropwise at reflux temperature and heated further for 1.5 hr. The progress of the reaction was monitored on TLC. The reaction mixture was cooled and added DM Water (6.0 L). The uppermost oily layer was separated, dissolved in ethyl acetate (3.4 L), and washed with DM water (3.4 L×3). The uppermost oily layer was separated, dried over sodium sulfate and evaporated to dryness to give the crude title compound (1.5 Kg). The crude product was employed in the next step without further purification,
