    Abstract: A method of manufacturing an amorphous form of the hemi-calcium salt of (3R, 5R) 7-[3-phenyl-4-phenylcarbamoyl-2-(4-fluorophenyl)-5-isopropyl-pyrrol-1-yl]-3,5-dihydroxyheptanoic acid of formula (I), in which (3R, 5R) 7-[3-phenyl-4-phenylcarbamoyl-2-(4-fluorophenyl)-5-isopropyl-pyrrol-1-yl]-3,5-dihydroxyheptanoic acid or its salt with a cation M + wherein M + is either a cation of an alkali metal or an ammonium cation of formula R n N (+) H (4-n) wherein R is lower C 1 -C 5 alkyl, n may reach values ranging between 0 and 3, is, without isolating the intermediate in the form of the hemi-calcium salt or of another salt, acid or lactone, converted, in a solution, by the treatment with the calcium salt or calcium hydroxide, or a calcium C 1 -C 5 alcoholate, to the hemi-calcium salt, and the latter is precipitated with a C 1 -C 5 hydrocarbon or dialkylether of formula R 1 OR 2 , wherein each of R 1 and R 2 is a C 1 -C 5 alkyl group. The starting acid or its salt is prepared starting from (3R, 5R) tert-butyl (6-{2-[3-phenyl-4-phenylcarbamoyl-2-(4-fluorophenyl)-5-isopropyl-pyrrol-1-yl]-ethyl}-2,2-dimethyl-[1,3]dioxane-4-yl)-acetate of formula II.
