Patent ID: 8227608

Claim:
A process for the preparation of a compound of Formula (II), the process comprising contacting a compound of Formula (I) with a hydrolysis agent to form the compound of Formula (II): wherein: R 1 , R 7 , R 8 , and R 9 are independently selected from the group consisting of hydrocarbyl and substituted hydrocarbyl; R 2 , and R 3 are independently selected from the group consisting of hydrogen, hydrocarbyl and substituted hydrocarbyl; R 4 and R 5 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, halogen, {—}OH, {—}NH 2 , {—}SH, {—}SR 7 , and {—}OR 7 ; R 6 is independently selected from the group consisting of hydrogen, a protecting group, hydrocarbyl, and substituted hydrocarbyl; and X is oxygen, and wherein the molar ratio of the compound of Formula (I) to the hydrolysis agent is from about 1:5 to about 1:9 and wherein the molar yield of Formula (II) is at least 65%.
