Procedure: In a 500 ml four-neck flask, load 115 g phenol (1.223 mol) and 82.2 g (1.468 mol) of dry KOH. A mass is heated up to 90° C. while mixing. Then by dropping during 0.5 h add 184.7 g (1.223 mol) of amylbromide. Maintain the mixture at a temperature of 95-100° C. for 45 minutes while mixing. After cooling, 200 ml of benzene and 300 ml of water are added to the mixture. The water layer is decanted. Then the benzene layer is washed with 200 ml of 5% solution of NaOH The benzene layer is then washed a few times with water until the reaction mixture is neutral. In a 500 ml four-neck flask, load while mixing Maintain the mixture at a temperature of 95-100° C. for 45 minutes while mixing After cooling The water layer is decanted Then the benzene layer is washed with 200 ml of 5% solution of NaOH The benzene layer is then washed a few times with water until the reaction mixture

Procedure: n-Pentyloxybenzene (Ia) and P4S10 (in a molar ratio of 10:1) were stirred for six hours at 150° C. under anhydrous conditions. The mixture was cooled, toluene was added, and the reaction flask was left for two days at 5° C. The resulting precipitate was recovered by filtration, washed with anhydrous ether and dried. The yield of product was 46% of theory; after recrystallization from chloroform/petroleum ether it melted at 144°-6° C. Its solubility in tetrahydrofuran was found to be 5 gms/100 ml at room temperature. The mixture was cooled The resulting precipitate was recovered by filtration washed with anhydrous ether dried after recrystallization from chloroform/petroleum ether it melted at 144°-6° C at room temperature

Procedure: Phenol (0.5 mole) was added to a solution of sodium ethoxide in ethanol (2 N; 250 ml) and 1-bromopentane (0.5 mole) was added dropwise while stirring. The mixture was heated under reflux for three hours and most of the solvent was then distilled off. Water was added to the residue and the organic layer was separated, washed twice with 10% aqueous NaOH, water, dilute H2SO4 and water, and was then dried over MgSO4. It was distilled in vacuo to give the title compound, b.p. 97°-101° C. at 14 mm Hg pressure. The identity and purity was confirmed by thin layer chromatography (TLC) and NMR and IR spectroscopy. was added dropwise The mixture was heated under reflux for three hours and most of the solvent was then distilled off Water was added to the residue the organic layer was separated washed twice with 10% aqueous NaOH, water, dilute H2SO4 and water was then dried over MgSO4 It was distilled in vacuo
