Sodium Bicarbonate → 3,5-Dichlorobenzyl 4-(tert-butoxycarbonylamino)piperidine-1-carboxylate

Participants

Reaction Steps

A solution of tert-butyl piperidin-4-ylcarbamate (2.0 g, 9.99 mmol) in DCM (40 ml) was treated with sodium bicarbonate solution (50 ml, 9.99 mmol) followed by a solution of 3,5-dichlorobenzyl carbonochloridate (2.392 g, 9.99 mmol) in DCM (10 ml). The reaction mixture was stirred vigorously at RT until gas evolution ceased. The organic layer was separated, dried over MgSO4 (anh), filtered and evaporated under reduced pressure, yielding the title compound as colourless oil that solidified on standing;
