Patent ID: 7057065

Claim:
A process of producing a compound of Formula IA: wherein each of R 1 –R 3 is independently selected from the group consisting of hydrogen, halogen and a substituted or unsubstituted alkyl group and aryl group, said process comprising reacting a compound of Formula II: wherein R 5 is a substituted or unsubstituted alkyl group and X is a halogen with an organosilyl halide of Formula III: R 4 4−n SiX n (III) wherein R 4 is selected from the group consisting of a substituted or unsubstituted alkyl group, aryl group, and alkoxy group and X is as defined above and n is an integer of from 1 to 3, to form an intermediate compound and reacting the intermediate compound with a proton donor to produce the compound of Formula IA.
