Abstract
Procedure for producing a prostaglandin compound of the formula: **(See formula)** where n is 1 to 8 and a is zero to 4; wherein R16 is hydrogen alkyl of 1 to 4 carbon atoms inclusive; where Y is isobutyl, tert-butyl, 3,3-difluoro-butyl, 4,4-difluorobutyl, or 4,4,4-trifluorobutyl and where it indicates binding of the group to the ring in alpha or beta configuration, characterized in that consists of dehydrating with acid a compound of the formula: **(See formula)** where R16, n, a, Y, and are defined as above, carrying out the operative process in successive phases as follows: a 200 mg solution of 19-methylprostaglandin E1 methyl ester, in a 2 ml mixture, of tetrahydrofuran and 2 ml, of 0.5N hydrochloric acid, stir in nitrogen, at 25ºC, for five days; the reaction mixture is then diluted with saturated aqueous sodium chloride solution and extracted with ethyl acetate; the ethyl acetate extract is washed with saturated aqueous sodium chloride solution; it is dried over sodium sulfate and evaporated to give 159 mg, of an oil; This is chromatographed on 25 g of silica gel and eluted with 350 ml of 20%, 400 ml of 30%, 500 ml of 40%, 1,000 ml of 50% and 500 ml of 60% acetate. of ethyl in Skellysolve B, and then with 500 ml of ethyl acetate, collecting 25 ml fractions; and eluate fractions 17-22 are concentrated and mixed to give 45 mg of 17-methyl-prostaglandin A1 methyl ester.
