A previously reported protocol for the synthesis of the commercial dye [Bu4N](2)[Ru(4-carboxy-4'-carboxylate-2,2'-bipyridine)(2)(NCS)(2)] (N719) was thoroughly optimized in terms of the amount of input materials needed, reaction times and temperatures achieving significant reductions in all the three synthetic steps. This optimization allowed a 81% reduction of the Sheldon's E factor of the overall process.
