In this example, Compound 1 of the Scheme 2 is coupled with compound 2 of Scheme 2 at the presence of an activating agent BOP to give product 3 of Scheme 2, which then alkylated with substituted benzyl bromide 4 of Scheme 2 to produce the desired product 6 of Scheme 2 and by product 5 of Scheme 2. Compound 6 of Scheme 2 is purified by a silica gel column and then reacted with TFA to cleave the Boc group. Compound 7 of Scheme 2 is alkylated with benzyl bromide, and the reaction mixture is purified by HPLC to yield final product compound of Formula I, which in the exemplified scheme is a white solid with purity >98%, overall yield about 32%.
