Procedure

The 4-(4-tert-butoxycarbonylaminopiperidin-1-yl)-cinnamic acid ethyl ester (126 g, 0.33 mol) obtained in Example 8 (1) was dissolved in ethanol (1 L), and 10% Pd—C (48.5 g) was added, followed by stirring in a hydrogen atmosphere for 18 hours. The insoluble material was filtered with Celite, and the filtrate was evaporated under reduced pressure, thereby obtaining 4-(4-tert-butoxycarbonylaminopiperidin-1-yl)-dihydrocinnamic acid ethyl ester (107 g, 85%) as a white solid.

Workup

  1. filtrationThe insoluble material was filtered with Celite
  2. customthe filtrate was evaporated under reduced pressure
