Procedure

4-Alpha-methylbenzylamino-1-methyl-piperidine (47AKU-36) DL-Phenylethylamine (606 mg, 5.0 mmol) was dissolved in 10 ml methanol and 1-Methyl-4-piperidone (566 mg, 5.0 mmol) in 10 ml methanol was added. Mixture was stirred and Acetic acid (˜0.75 ml) was added until pH˜5. NaCNBH3 (628 g, 10 mmol) was slowly added. Gas evolution observed. After magnetic stirring for 20 hrs methanol was partly removed on Rotavapor (40° C.). Ethylacetate, 2M NaOH and water were added until pH˜10. Phases were separated and aq. phase was then re-extracted with ethylacetate and dichloromethane. Combined organic phases were dried over MgSO4. Concentration on Rotavapor (40° C.) yielded 838 mg crude 47AKU-36. TLC (10% methanol in dichloromethane): Rf=0.3. HPLC-MS (Method A): M+=219.1 (UV/MS(%)=100/94).
