Abstract

PGF2alpha-tris- (hydroxy-methyl)-amino-methane is prepd. (a) tris-(hydroxy-methyl) -amino-methane and water is added to liq. or solid PGF2alpha at 25-35 deg.C. The mixt. is agitated until it is homogeneous. Water miscible solvent is added in which the prod. is not or only barely soluble. The mixt. is cooled to -10 - +10 deg.C and opt. seeded. Addn. of solvent is stopped when crystallisation of PGF2alpha is complete. (b) Water is removed under vacuum or opt. by azeotropic distn. from the homogeneous aq. phase prepd. in (a). The residue is dissolved in methanol and the soln. is also treated as in (
