Procedure

The compound of Example 166 (170 mg, 0.512 mmol) was dissolved in ethyl acetate. Formic acid (61 μL, 1.53 mmol) was added and the mixture was heated at 80° C. for 3 h. After cooling to room temperature, the reaction mixture was extracted three times with water, dried (sodium sulfate), filtered and evaporated to dryness. 1H NMR(CDCl3, 300 MHz): 1.43(s, 18H); 2.50, 2.65(2dd, J1=16.7 Hz, J2=6.2 Hz, 4H); 3.20(p, J=6.2 Hz, 1H).
