実験手順

In analogy to Example 1, paragraph d), 7.63 g of dimethyl (o-methoxyphenoxy)malonate and 5.6 g of p-methoxy-benzamidine hydrochloride were condensed to give 2-(p-methoxyphenyl)-5-(o-methoxyphenoxy)-6-hydroxy-4(3H)-pyrimidinone. Reaction of this compound in analogy to Example 1, paragraph e), yielded 4,6-dichloro-2-(p-methoxyphenyl)-5-(o-methoxyphenoxy)-pyrimidine, m.p. 113°-114° C., from which in analogy to Example 1, paragraph f), there was obtained p-tert-butyl-N-[6-chloro-5-(o-methoxyphenoxy)-2-(p-methoxyphenyl)-4-pyrimidinyl]benzenesulfonamide, m.p. 221°-222° C.
