(compound B), a fluorinated diether derived from the anesthetic sevoflurane, was reacted with bromine trifluoride. With proper control of reaction temperature, a single product, 1,2-bis(fluoromethoxy)-1,1,3,3,3-pentafluoropropane (BFPP), was obtained in 58% yield. In the rat model, BFPP exhibited enhanced metabolic stability both in vivo and in liver microsomal preparations, evidenced by a reduction in
