2-chloro-N-propylaniline

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

Procedure: A solution of 25.4 g. 2-chloro-N-propylaniline and 15.15 g. dry triethylamine in 200 ml. dry ether was added to a solution of 13 ml. thiophosgene in 200 ml. of the same solvent at -20° C. The reaction mixture was allowed to warm to room temperature and then filtered, the filtered solid being washed with ether. The ethereal extract was added to the ethereal liquor and after drying over sodium sulphate, was evaporated to give a dark oil. On standing further solid precipitated, which was then separated from the oil. The oily filtrate was distilled to give the product N-2-chlorophenyl-N-propyl(thiocarbamoyl) chloride, b.p. 119°-120° C./0.4 mm. Hg. at -20° C filtered the filtered solid being washed with ether The ethereal extract was added to the ethereal liquor after drying over sodium sulphate was evaporated to give a dark oil precipitated which was then separated from the oil The oily filtrate was distilled

Procedure: A solution of 255g. 2-chloroacetanilide in 900 ml. dry tetrahydrofuran was added to a water-cooled stirred suspension of 75g. sodium hydride (50 percent w/w) in the same solvent. When the evolution of hydrogen had ceased, the mixture was stirred for 10 minutes and 140 ml. propyl bromide was added dropwise. The mixture was refluxed for two hours before 50 ml. propyl bromide was added and the heating was continued for another 16 hours. The precipitate of sodium bromide was collected and washed with dry tetrahydrofuran. Evaporation of the organic filtrate gave an oil which was heated under reflux with 750 ml. concentrated hydrochloric acid and 750 ml. industrial methylated spirits for 46 hours. Further additions of 250 ml. and 125 ml. portions of concentrated hydrochloric acid were made after 19 and 27 hours heating respectively. The organic solvents were removed under reduced pressure and the cooled acid solution was basified with concentrated sodium hydroxide solution. The organic layer was isolated by ether extraction and the dried ether solution evaporated to give an oil. Distillation gave 2-chloro-N-propylaniline as the oily product, boiling point 89°-92° C./3.0 mm. Hg. cooled the mixture was stirred for 10 minutes The mixture was refluxed for two hours before 50 ml The precipitate of sodium bromide was collected washed with dry tetrahydrofuran Evaporation of the organic filtrate gave an oil which was heated under reflux with 750 ml after 19 and 27 hours heating respectively The organic solvents were removed under reduced pressure The organic layer was isolated by ether extraction the dried ether solution evaporated to give an oil Distillation
