Procedure

4-Methylbenzylamine (607 mg, 5.0 mmol) was dissolved in 10 ml methanol and placed in 100 ml flask. Tropinone (697 mg, 5.0 mmol) in 10 ml methanol was added. Acetic acid (0.75 ml) was added until pH˜5. NaCNBH3 (628 mg, 10 mmol) was slowly added. Gas evolution observed. After 20 hrs magnetic stirring dichloromethane, 2M NaOH and water were added until pH˜10. Phases were separated and aq. phase was then re-extracted with dichloromethane. Combined organic phases were dried over MgSO4. Concentration on Rotavapor (40° C.) yielded 1.14 g crude 47AKU-17. TLC (10% methanol in dichloromethane): Rf=0.4. HPLC-MS (Method A): M+=245.2 (UV/MS(%)=65/96).
