Procedure

To a solution of 2-(6-((3aR,6aS)-5-(2-((tert-butyldimethylsilyl)oxy)ethyl)hexahydropyrrolo[3,4-c]pyrrol-2(1H)-yl)pyridazin-3-yl)-5-(1H-pyrazol-4-yl)phenol (20 mg, 0.039 mmol) in dioxane (2 mL) was added 4N HCl in dioxane (1 mL, 4.00 mmol). The reaction mixture was stirred at RT overnight, then basified with 2N NH3 in MeOH and concentrated. The crude product was purified via preparative HPLC to give an off-white solid 2-(6-((3aR,6aS)-5-(2-hydroxyethyl)hexahydropyrrolo[3,4-c]pyrrol-2(1H)-yl)pyridazin-3-yl)-5-(1H-pyrazol-4-yl)phenol (6.5 mg, 0.016 mmol, 41% yield). LCMS Rt=0.87 min [Method Q]; MS (M+1)=393.1. 1H NMR (400 MHz, METHANOL-d4) δ ppm 8.01 (d, J=9.60 Hz, 1H), 7.93 (s, 2H), 7.69 (d, J=8.08 Hz, 1H), 7.08-7.19 (m, 3H), 3.67-3.77 (m, 4H), 3.56 (d, J=11.12 Hz, 2H), 3.11 (br. s., 2H), 2.97-3.05 (m, 2H), 2.72 (t, J=5.81 Hz, 2H), 2.63-2.70 (m, 2H).
