Procedure

To a solution of (3-carbamoyl-pyrazolo[3,4-c]pyridin-1-yl)-acetic acid trifluoroacetate salt (2.12 g, 6.35 mmol, prepared as described in Scheme A26) in DMF (32 mL) were successively added (1R,3S,5R)—N-(3-chloro-2-fluorobenzyl)-2-azabicyclo[3.1.0]hexane-3-carboxamide trifluoroacetate salt (2.70 g, 6.35 mmol), HBTU (3.37 g, 8.89 mmol) and DIPEA (4.44 mL, 25.4 mmol). The reaction mixture was stirred at RT for 16 h, and then was concentrated under vacuum. The residual oil was partitioned between CH2Cl2 and a sat. aq. NaHCO3 solution. A solid precipitated from the resulting emulsion and was filtered off, washed with water and dried under vacuum. The solid was suspended in a mixture of water (150 mL) and MeOH (3 mL), stirred for 1 h at RT, filtered, washed with water and finally dried under vacuum to give the title material as a white powder. MS (LC/MS): 471 [M+H]+; tR (HPLC conditions c): 3.41 min.
