CP-885,316 (1), an imidazo[4,5-c]pyridine, 4, was prepared from 3,4-diaminopyridine (9). Two routes were demonstrated using the regioselective introduction of either an acetamide at the 3-position or a tert-butylcarbamate at the 4-position.
由3,4-二氨基吡啶(9)制备CP-885,316(1),咪唑并[4,5- c ]吡啶4。使用在3-位的乙酰胺或在4-位的叔丁基氨基甲酸酯的区域选择性引入证明了两种途径。
