Procedure

Following the procedure as described in Example 2, making variation as required to use N-benzyl-4-methyl-2-(2-oxopiperidin-1-yl)thiazole-5-carboxamide in place of N-(4-fluorobenzyl)-4-methyl-2-(2-oxopyrrolidin-1-yl)thiazole-5-carboxamide to react with 1-(bromomethyl)-4-methoxybenzene in place of 1-(bromomethyl)-4-(trifluoromethyl)benzene, the title compound was obtained as a white solid in 28% yield: mp 116-118° C.
