Reaction Steps

4-(4-chloro-phenyl-amino)-1-(phenylmethyl)-4-piperidine-carboxamide (6.47 g) was dissolved in 31 ml triethyl orthoformate and stirred at 150° C. for 10 d. After cooling to 0° C., the reaction mixture was filtered and the light brown powder washed with ether to yield 8-benzyl-1-4-chloro-phenyl-1,3,8-triazaspiro[4,5]dec-2-en-4-one (3.90 g). M.p. 217-219° C.
