Reaction Steps

A premixed solution of cyclopentanol (33.5 mg, 0.389 mmol) and Hunig's base (57 uL) in CH2Cl2 (1 mL) was slowly added to a solution of triphosgene (38.5 mg, 0.130 mmol) in CH2Cl2 (1 mL), and the resulting solution was stirred for 1 hour. A premixed solution of 4-{2-amino-6-[(3R)-3-amino-1-piperidinyl]-4-pyrimidinyl}-2-fluorobenzonitrile (125 mg, 0.324 mmol) and Hunig's base (226 uL) in CH2Cl2 (5 mL) was added, and the reaction mixture was stirred at room temperature overnight. The reaction was concentrated, then loaded on a Biotage SNAP 10 g column and purified with a gradient of 0 to 55% EtOAc in Hexane over 25 min. LC-MS (ES) m/z=425 [M+H]+.
