Procedure

The procedure described in Example 12f was followed with the piperidine obtained in step e (0.042 g, 0.109 mmol) and TFA (1.5 mL) in CH2Cl2 (6 mL), Na2CO3 (0.058 g, 0.545 mmol) and benzyl bromide (0.016 mL, 0,131 mmol) in DMF (6 mL). After purification by chromatography (1-10% MeOH-CH2Cl2), the title compound (0.018 g, 44%) was obtained as an off-white solid.
