Participants

Reaction Steps

The title compound was prepared by a similar process to that described for Example 6 but using isocyano(4-methoxyphenyl)methyl 4-methylphenyl sulfone (Intermediate 104) in place of PhTosMIC and N-[4-(methylthio)thieno[2,3-d]pyrimidin-6-ylmethylidene]methanamine (intermediate 16) in place of N-(3,4-dimethoxybenzyl)-N-[thieno[2,3-d]pyrimidin-6-ylmethylidene]amine (intermediate 14) to afford the title compound as a solid (2.69 g, 39%);
