Reaction Steps

A mixture of 1-(((3S,5S)-5-methyl-1-oxaspiro[2.5]octan-5-yl)methyl)-1H-benzo[d]imidazole-6-carbonitrile (100 mg, 0.355 mmol) and 4,6-bis(methyloxy)-3-pyridinamine (110 mg, 0.711 mmol) in isopropanol (10 mL) was heated to reflux overnight. The reaction mixture was cooled to RT, and solvent was removed. The residue was redissolved in DCM and hexane was added. The solvent was removed, and the residue was purified via silica gel chromatography (ISCO, 40 g Silica, 40 mL/min, 0%-10% MeOH/CH2Cl2). Fractions with product were collected and concentrated to afford 1-(((1S,3S)-3-(((4,6-dimethoxypyridin-3-yl)amino)methyl)-3-hydroxy-1-methylcyclohexaneyl)methyl)-1H-benzo[d]imidazole-6-carbonitrile (100 mg, 64.6% yield). MS (m/z) 436 (M+H+).
