The present invention provides a novel α-fluoromethoxycarboxylic ester represented by Formula (1): (CF3)2C(OCH2F)COOR wherein R is a hydrocarbon group that may have a substituent; a process for producing 1,1,1,3,3,3-hexafluoroisopropyl fluoromethyl ether, the process including hydrolyzing and decarboxylating the α-fluoromethoxycarboxylic ester; and a process for producing an α-fluoromethoxycarboxylic ester represented by Formula (1): (CF3)2C (OCH2F)COOR, the process including reacting an α-hydroxycarboxylic ester represented by Formula (2): (CF3)2C(OH)COOR with a halofluoromethane in the presence of an alkaline compound. According to the present invention, 1,1,1,3,3,3-hexafluoroisopropyl fluoromethyl ether (sevoflurane), which is known as an anesthetic compound, can be efficiently produced at low cost.
