Participants

Reaction Steps

Following the procedure as described in Example 1, making variations only as required to use pyridin-3-ylmethanamine in place of benzylamine to react with 2-(4-(2-cyclopropylethoxy)-2-oxopyridin-1(2H)-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as a colorless solid in 47% yield: mp 170-172° C.
