Reaction Conditions

Reaction Steps

To a cooled (0° C.) solution of dipropargylamine (46.7 g, 502 mmol) in EtOAc (200 mL) and 10% aqueous K2CO3 (700 mL, 507 mmol) was slowly added a solution of N-(benzyloxycarbonyloxy)succinimide (125 g, 502 mmol) in EtOAc (500 mL) over 20 mins. The solution was stirred at 0° C. for 2 h then at RT 16 h. The phases were separated and the organic phase was washed with 10% aqueous K2CO3 (700 mL, 507 mmol) and then with saturated brine (500 mL) and was diluted to 1000 mL with EtOAc to give a 0.5M solution.
