Reaction Steps

To a mixture of tert-butyl 4-{[4-amino-3-(4-amino-3-methoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl}-4-hydroxy-1-piperidinecarboxylate (0.08 g, 0.00017 mol) in pyridine (4 mL) was added trans-2-phenyl-cyclopropane carbonyl chloride (0.035 g, 0.00019 mol) at −5° C. The mixture was stirred at −5° C. for 10 minutes then warmed up to room temperature to stir for 1 hours. The mixture was quenched with an aqueous 1N solution of sodium hydroxide. Pyridine was removed under reduced pressure. The residue was partitioned between water and dichloromethane (50 mL). The organic layer was washed with water. The solvents were removed under reduced and the residue was purified by RP-HPLC (Hypersilprep HS C18, 8 μm, 250×21.1 mm; 5%-100% over 35 min with 0.1 M ammonium acetate, 21 mL/min) to yield trans tert-butyl 4-{[4-amino-3-(3-methoxy-4-{[(2-phenylcyclopropyl)carbonyl]amino}phenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl}-4-hydroxy-1-piperidinecarboxylate (0.08 g, 0.00013 mol).
