More Information
Summary:A Process is disclosed for preparing a compound of the Formula (I)which comprises the steps of:(a) detritylating a compound of the Formula (III)with 0.1 to 1 equivalent of potassium hydroxide in a C1 to C4 straight chain alcohol solvent to obtain a reaction mixture containing the compound of the Formula (I),(b) changing the C1 to C4 straight chain alcohol solvent in the reaction mixture to an aprotic solvent or a weakly protic solvent, and(c) following step (b) crystallizing out the compound of the Formula (I) from the reaction mixture.
