Procedure

A solution of the product of Example 11 (5.0 g), piperidine (3.1 mL), and acetic acid (2.0 mL) in DCE (100 mL) was treated with sodium triacetoxyborohydride (9.3 g). After 16 h, the resulting mixture was diluted with water (100 mL) and extracted with DCM (3×50 mL). The combined organic phases were dried (magnesium sulfate) and evaporated, giving the title compound as an amber oil (5.3 g).
