Reaction Steps
Aminocyclohexanol hydrochloride (6.3 g, 41.6 mmol) and triethylamine (11.6 mL, 83.1 mmol) were stirred in toluene (150 mL) at room temperature for 1 hour. To this was added phthalic anhydride (7.4 g, 49.9 mmol) and the reaction mixture was stirred at 120-130° C. The by-product water was removed from the reaction mixture. Toluene was concentrated under reduced pressure. The crude compound thus obtained was purified by column chromatography using ether in hexane solvent mixture (2:1) as eluent to furnish the title compound (8.5 g, 84%).
