BENZYL ETHYL PIPERIDINE-1,3-DICARBOXYLATE Use and Manufacturing

Step 1: [00248] Step A: To ethyl piperidine-3 -carboxylate (5.0 g, 30.2 mmol) and KTo a solution of ethyl piperidine-3-carboxylate (4 g, 25.4 mmol) in THF (30 mL) and water (30.0 mL) was added a2C03 (6.74 g, 63.6 mmol). The resulting suspension was stirred at rt for 20 min. After this time, benzyl carbonochloridate (4.12 g, 24.17 mmol) was added dropwise. After addition, the stirring solution became milky, and a white precipitate formed. After stirring at rt for 2h, the reaction was partitioned between EtOAc and water. The separated aqueous phase was extracted with EtOAc (2x). The combined organics were washed with water and saturated aqueous NaCl. The organic layer was dried over NaStep 1. 1-Benzyl 3-ethyl piperidine-1, 3-dicarboxylate; A 250-mL round-bottomed flask was charged with a solution of NaHCO
