Participants

Reaction Steps

Phenyl isothiocyanate (203 mg, 1.50 mmol) was added to a solution of 1,3-dibenzyl-1,4,8-triazaspiro[4,5]decan-2-one (505 mg, 1.50 mmol) in toluene (14.3 ml) with stirring under a blanket of nitrogen at RT and the reaction mixture was stirred at 50° C. for 8 h. After removal of the solvent, the desired product 1,3-dibenzyl-2-oxo-1,4,8-triazaspiro[4,5]decane-8-thiocarboxylic acid phenylamide was obtained by means of preparative HPLC.
