tert-butoxybis(dimethylamino)methane was carried out on methyl substituted six-membered nitrogen containing heterocycles 1 to give enamines 2, which were easily transformed to oximes by treating with hydroxylamine hydrochloride in methanol. Most of them were isolated as (E, Z)-oximes of heteroarylacetaldehyde (11), but 5-(1,2,4-triazinyl) substituted derivatives as (E, Z)-oximes of 2,5-dihydro-1,2,4-triaz
