Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of 52 g 2-propylpentanol and 86 g of p-toluenesulfonic acid in 175 ml of chloroform was added at 0°-3° C. and under N2 -atmosphere 48 g of pyridine. The mixture was kept at 0° C. for 30 minutes and at room temperature for 19 hrs. After cooling the reaction mixture, 3M HCl (300 ml) was added. The organic phase was separated and washed with water and brine. Drying with Na2SO4 and evaporation gives 110 g of 2-propylpentyl tosylate. was added The organic phase was separated washed with water and brine Drying with Na2SO4 and evaporation

Procedure: Phosphorus tribromide (33.3 g, 0.123 mol) was added dropwise to 2-propyl-1-pentanol (40 g, 0.307 mol) at −10° C. to maintain the temperature below 0° C. and the mixture was stirred overnight at room temperature. The reaction mixture was heated at 100° C. for 1 h, cooled to room temperature, and poured into ice water (250 ml). The organic layer was separated, washed with conc. H2SO4 (25 ml) followed by saturated K2CO3 (25 ml), dried and distilled in vacuo (80° C./15 mm Hg) to furnish 40 g (83%) of 1-bromo-2-propylpentane. to maintain the temperature below 0° C. The reaction mixture was heated at 100° C. for 1 h cooled to room temperature The organic layer was separated washed with conc. H2SO4 (25 ml) dried distilled in vacuo (80° C./15 mm Hg)
