Reaction Steps
To a solution of aceton cyanohydrin (2.3 g, 27 mmol) saturated with ammonia, 1,7-dichloro-4-heptanone (0.50 g, 2.7 mmol) was added dropwise at 20° C. The resulting solution was stirred for 48 hours at 20° C. under ammonia gas atmosphere. To the reaction mixture, 0.1N-NaOH was added to extract with methylene chloride. The extract was dried over anhydrous sodium sulfate, concentrated and distilled in vacuo to afford 0.33 g of the desired compound (Yield: 89%).
