Patent ID: 8410265

Claim:
A process of preparing a compound of Formula XII: comprising reacting a compound of Formula X: with a compound of Formula XIII: in the presence of a palladium catalyst, base, and a solvent, to form a compound of Formula XII; wherein: X 2 is a tosylate group, a triflate group, iodo, chloro, or bromo; and R c and R d are each independently H or C 1-6 alkyl; or R c and R d , together with the oxygen atoms to which they are attached and the boron atom to which the oxygen atoms are attached, form a 5- to 6-membered heterocyclic ring, which is optionally substituted with 1, 2, 3, or 4 C 14 alkyl groups; P 1 is independently a protecting group; and P 2 is a protecting group selected from the group consisting of 1-(ethoxy)ethyl, p-methoxybenzyl, triphenylmethyl, diphenylmethyl, hydroxymethyl, methoxymethyl, and t-butyldimethylsilylmethyl.
