Procedure

Methanol (50 mL) was cooled in an ice bath and SOCl2 (2 mL) was added dropwise with stirring. After 15 min, 2-(3-(tert-butoxycarbonyl)-3-azaspiro[5.5]undecan-9-yl)acetic acid (0.34 g, purchased from WuXi Pharmatech) was added. The mixture was stirred at rt for 2 d and concentrated to afford methyl 2-(3-azaspiro[5.5]undecan-9-yl)acetate as its hydrochloride salt.

Workup

  1. stirringThe mixture was stirred at rt for 2 d
