Reaction Steps

Compound X was prepared by a method analogous to that described in Example 1 by substituting 6-(dimethylamino)pyridin-3-ylboronic acid for 1H-indol-5-ylboronic acid in the reaction with Intermediate A and 6-(dimethylamino)pyridin-3-ylboronic acid for 3,4,5-trimethoxyphenylboronic acid in the reaction with Intermediate B. HPLC retention time: 1.17 minutes. MS ESI (m/z): 359.4 (M+H)+, calc. 358.
