Reaction Steps

Trimethylsilyldiazomethane (2 M in diethyl ether) was added slowly to a stirred solution of N-[1-(2-chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]glycine (Step 1) (0.80 g, 2.63 mmol) in DCM (4 mL) and MeOH (1 mL) until a yellow colour persisted. A few drops of acetic acid was added after 1 minute followed by the addition of DCM and water. The two phases were separated and the organic phase was concentrated in vacuo to give the title compound (795 mg), 1H NMR (300 MHz, CD3OD) δ 8.32 (s, 1H), 8.24 (s, 1H), 7.66 (m, 1H), 7.54 (m, 3H), 4.39 (s, 2H), 3.77 (s, 3H).
