Abstract: A silyl cpd. of formula (I) is prepd. by reacting an ester cpd. of formula (II) with a halosilan cpd. of formula M-(CH2)n- Si (X)(Y)(Z) in the presence of solvent i.e. DMF, MeOH and base i.e. NaOH, Na2CO3 at 10-30 deg. C. In the formulas, R1=H or trityl gp.; R2= carboxy or methylester gp.; M=I; X= Y= Z= Me; n=1. (I) is useful as an intermediate for the prodn. of cephalosporin cpds.
