The substantially same method as described in Example 371 was conducted, except that (1S,2R)-3-(benzyloxy)-1-(2-chlorophenyl)propane-1,2-diol (Preparation example 375) was used instead of that (±)-3-(benzyloxy)-1-(2-chlorophenyl)propane-1,2-diol (Preparation example 370), to obtain the title compound (0.84 g, 85%).
