Participants

Reaction Conditions

Reaction Steps

1.1 g of Br2 in 10 ml of methylene chloride is put in drop by drop into a stirred solution of 1.8 g (15 mmol) of triphenylphosphine in 50 ml of methylene chloride at 0° C. Then, 2 g of 5-phenoxy-4-methoxymethyl-beta-carboline-3-carboxamide and 1.9 ml of triethylamine are added. The reaction mixture is stirred for 1 hour at 0° C. and then vigorously stirred with 25 ml of methylene chloride and 25 ml of water for 5 minutes. After removal of the aqueous phase from the organic phase by concentration, 0.8 g of the desired product is obtained.
