Process for the preparation of the crystalline Form I of the orlistat, in which the Form I of the orlistat is a crystalline form of the orlistat that can be obtained by recrystallization of the orlistat with hydrocarbons, as described in U.S. Pat. No. 6,156,911; Tetrahedron letters, 1989, 30, 1833; J. Org. Chem., 1991, 56, 4714; and Helv. Chim. Minutes 1987, 70, 1412, including the process: a. obtaining a molten from orlistat; and b. drying of the melt to obtain Form I of the orlistat. |
