摘要：
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.
