Example 20 2-Chloro-4-(3-endo-hydroxy-8-azabicyclo[3.2.1]oct-8-yl)benzonitrile (196MBT8-B) Nortropine (269 mg, 2.12 mmol) and 2-chloro-4-fluorobenzonitrile (100 mg, 0.643 mmol) were dissolved in pyridine (2 mL). The mixture was heated to 110 C. in a sealed flask for 20 hours and then concentrated. The residue was dissolved in 2 M HCl (20 mL) and extracted with dichloromethane (2×20 mL). The combined organic phases were dried over Na2SO4, filtered and evaporated, and the resulting oil was purified by preparative TLC (eluting with dichloromethane) to afford 107 mg (63%) of the title compound as a colorless solid. LC/MS m/z 263 [M+H]+. 1H-NMR (CDCl3) delta 7.46-6.51 (m, 3H), 4.29-4.16 (m, 2H), 4.16-4.00 (m, 1H), 2.45-2.27 (m, 2H), 2.18-1.96 (m, 4H), 1.79-1.65 (m, 2H), 1.56 (s, 1H).
The synthetic route of 60702-69-4 has been constantly updated, and we look forward to future research findings.
