Procedure
A flask was charged with N2-[4-(1-benzyl-4-oxido-1,4-azaphosphinan-4-yl)-2-methoxyphenyl]-5-chloro-N4-[2-(propan-2-ylsulfonyl)phenyl]pyrimidine-2,4-diamine (40.0 mg, 0.0625 mmol) and 10% Pd—C (40.0 mg). The flask was evacuated and filled with nitrogen. Anhydrous methanol (2 mL) was added to the flask and the flask was equipped with a reflux condenser with a nitrogen inlet. Ammonium formate (31.5 mg, 0.500 mmol) was added in one portion at room temperature. The resulting mixture was stirred at reflux for 3 h. The reaction was filtered through a Celite pad and the Celite was washed with 2×5 mL methanol. The combined filtrate and washing was evaporated in vacuo. The crude residue was purified by prep-HPLC to afford the final compound (13.6 mg, 42% yield). MS/ES+: m/z=516.
