(2R)-pyrrolidine-2-carbonitrile;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In analogy to the procedure described for the synthesis of 5-tert-butyl-3-(2-chloro-benzyl)-7-morpholin-4-yl-3H-[1,2,3]triazolo[4,5-d]pyrimidine (example 1, step c), the title compound was prepared from 5-tert-butyl-7-chloro-3-(2-chlorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and (R)-pyrrolidine-2-carbonitrile hydrochloride and isolated as light-yellow solid (9.7 mg, 52%). MS (m/e): 396.4 (MH+).

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: (R)-2-(6-Chloro-3-oxopyrrolo[4,3,2-de][2,6]naphthyridin-4(1H,3H,5H)-yl)-3-methylbutanoic acid (10 mg, 0.032 mmol), HATU (15 mg, 0.039 mmol), (R)-pyrrolidine-2-carbonitrile hydrochloride (4 mg, 0.032 mmol), and N-methylmorpholine (90 μL, 0.097 mmol) were combined in THF (0.5 mL). The reaction mixture was stirred under nitrogen at 40° C. for 10 min and then at room temperature for 30 min. The solution was concentrated and purified by preparative HPLC (10-50% AcCN/H2O with 0.035% TFA) to afford the title compound as a white solid (2 mg, 18%). 1H NMR (500 MHz, CD3OD) δ 0.94 (d, J=6.9 Hz, 3H), 1.06 (d, J=6.3 Hz, 3H), 1.03-1.12 (m, 1H), 2.12-2.17 (m, 2H), 2.25-2.27 (m, 2H), 2.59-2.63 (m, 1H), 3.72-3.74 (m, 1H), 3.83-3.86 (m, 1H), 4.92 (d, J=5.9 Hz, 1H), 5.06 (d, J=13.2 Hz, 1H), 5.46 (d, J=11.8 Hz, 1H), 7.86 (s, 1H), 8.25 (s, 1H). [M+H] calc'd for C19H20ClN5O2, 386; found, 386. at room temperature for 30 min The solution was concentrated purified by preparative HPLC (10-50% AcCN/H2O with 0.035% TFA)
