Reaction Steps

A solution of LAH (1 M in THF, 0.57 mL) was slowly added at −10° C. under argon atmosphere to a solution of 1-[2-(4-hydroxycyclohexylamino)-pyrimidin-4-yl]-1H-indole-4-carboxylic acid methyl ester (100 mg) in THF (0.3 mL). The resulting mixture was stirred at −10° C. for 30 min, and at RT overnight. The reaction mixture was then cooled to 0° C. and water (20 μL) was added, followed by aqueous NaOH (15%, 20 μL) and a second aliquot of water (70 μL). The resulting mixture was stirred for 30 min, then filtered through a CELITE™ pad. The inorganic salts were triturated, the supernatant added to the filtrate, and the solution evaporated under reduced pressure to give trans-4-[4-(4-hydroxymethylindol-1-yl)-pyrimidin-2-ylamino]-cyclohexanol (32.5 g, 35% yield) as a white solid. MS=339 [M+H]+; MP=212.0-213.3° C.
