Ethyl 2-(4-acetyl-3,4-dihydro-2H-benzo[b][1,4]oxazin-6-yl)-5-phenylthiazole-4-carboxylate (7E) was prepared following a similar procedure as that described in example 1, except ethyl 2-(4-acetyl-3,4-dihydro-2H-benzo[b][1,4]oxazin-6-yl)-5-chlorothiazole-4-carboxylate (7D) was used instead of ethyl 2-(1-acetyl-1,2,3,4-tetrahydroquinolin-7-yl)-5-chlorothiazole-4-carboxylate (1J) and phenylboronic acid was used instead of 4-methoxyphenylboronic acid in step 11 of example 1.
