Procedure

(3R)—N,N-Dimethylpyrrolidin-3-amine (12.4 mg, 0.109 mmol) and N,N-diisopropylethylamine (14.5 mg, 0.109 mmol) were added to a solution of 4-chloro-3-[1-(4-ethylphenyl)-1H-imidazol-5-yl]-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (C22) (37 mg, 0.11 mmol) in acetonitrile (1 mL), and the reaction mixture was stirred at room temperature for 2 hours. After removal of volatiles in vacuo, the residue was chromatographed on silica gel (Gradient: 0% to 15% ethyl acetate in methanol) to afford the product as a glass. Yield: 13 mg, 0.031 mmol, 28%. LCMS m/z 417.1 (M+1). 1H NMR (500 MHz, CDCl3), characteristic peaks: δ 1.17 (t, J=7.6 Hz, 3H), 2.49-2.65 (m, 8H), 3.51-3.61 (br m, 1H), 3.72-3.81 (br m, 1H), 4.08 (s, 3H), 7.10 (br d, J=8.3 Hz, 2H), 7.22-7.29 (m, 2H, assumed; partially obscured by solvent peak), 7.40 (br s, 1H), 7.90 (br s, 1H), 8.29 (s, 1H).
