Reaction Steps

trans-4-Aminocyclohexanol (0.45 g, 4 mmol) was added to 3-(2-chloropyrimidin-4-yl)-1-methyl-1H-indole (0.23 g, 1 mmol) in NMP (8 mL), and the resulting mixture heated to 120° C. for 3 h. A second aliquot of trans-4-aminocyclohexanol (0.16 g, 1 mmol) was added, and the resulting mixture was heated to 130° C. The reaction mixture was cooled and partitioned between water and EtOAc, the organic layer separated, washed twice with water, dried over Na2SO4, filtered, and concentrated under reduced pressure. The crude residue was recrystallized from DCM/EtOAc/hexanes to give trans-4-[4-(1-methyl-1H-indol-3-yl)-pyrimidin-2-ylamino]-cyclo-hexanol (148 mg, 46% yield) as a light-yellow solid. MS=323 [M+H]+; MP=194.5-195.3° C.
