Reaction Steps

To 0.70 g (0.0022 mol) of the product obtained in Step B, dissolved in 10 mL toluene, was added 0.625 g (0.0030 mol) α,α,α-trifluoro-p-tolylisocyanate and 0.30 g (0.0029 mol) triethylamine. The reaction mixture was heated at reflux for 18 h, cooled to room temperature and concentrated under reduced pressure. The crude product was triturated with ether to afford 0.50 g of a white solid, mp 183°-184° C.
