4-((Benzyl(methyl)amino)methyl)-2-((2,6-difluorobenzyl)(ethoxycarbonyl)amino)-5-(4-(3-methoxyureido)phenyl)thiophene-3-carboxylic acid → N-(4-(5-((benzyl(methyl)amino)methyl)-1-(2,6-difluorobenzyl)-3-(4-hydroxycyclohexyl)-2,4-dioxo-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidin-6-yl)phenyl)-N'-methoxyurea

Participants

Reaction Steps

The similar reaction as described in Example 5 by using 4-(N-benzyl-N-methylaminomethyl)-2-[N-(2,6-difluorobenzyl)-N-ethoxycarbonylamino]-5-[4-(3-methoxyureido)phenyl]thiophene-3-carboxylic acid (3.19 g, 5 mmol) and trans-4-aminocyclohexanol (1.44 g, 12.5 mmol) gave the title compound (1.80 g, 52%) as colorless crystals.
