Procedure
The substantially same method as described in Example 372 was conducted, except that ((4S,5R)-4-(benzyloxymethyl)-5-(2-chlorophenyl)-2,2-dimethyl-1,3-dioxolane (Preparation example 376) was used instead of that (±)-4-(benzyloxymethyl)-5-(2-chlorophenyl)-2,2-dimethyl-1,3-dioxolane (Preparation example 371), to obtain the title compound (0.58 g, 95%).
