Procedure

The reaction was performed in same manner as in Example 307 using (S)-α-(2′-(2,3-epoxypropan-1-yloxy)benzylidene)-γ-butyrolactone (1.0 g) and 4-(4-chloro-3-trifluoromethylphenyl) -piperidine (0.8 g) in methanol (50 ml), and the obtained oil was treated with methanol/hydrochloric acid to give the title compound (0.45 g), melting point 172-174° C.
