In DMF (10 mL) was dissolved 4-((3-chloro-4-methoxybenzyl)amino)-2-(5H-pyrrolo[3,4-b]pyridin-6(7H)yl)-5-pyrimidine formic acid (0.8 g, 1.94 mmol). The solution was cooled in an ice bath. HATU (1.11 g, 2.91 mmol) and DIPEA (0.37 g, 2.87 mmol) were added. After 20 min, trans-4-aminocyclohexanol (0.27 g, 2.3 mmol) was added in batches. The reaction was conducted overnight. LC-MS was used to monitor the reaction. The reaction mixture was poured into water (50 mL) and filtrated. The solid was recrystallized with acetone (20 mL) to give N-((trans)-4-hydroxycyclohexan-1-yl)-4-((3-chloro-4-methoxybenzyl)amino)-2-(5H-pyrrolo[3,4-b]pyridin-6(7H)yl)-5-pyrimidine formamide (300 mg, 30.3% yield).
