Procedure

The same procedure as in Preparation Example 3 was repeated, with the exception that 1-(2-chlorophenyl)-2-(1,2,3,4-tetrazol-2-yl)ethan-1-one, prepared in Preparation Example 2, was used instead of 1-(2-chlorophenyl)-2-(1,2,3,4-tetrazol-1-yl)ethan-1-one, to afford (R)-1-(2-chlorophenyl)-2-(1,2,3,4-tetrazol-2-yl)ethan-1-ol (hereinafter referred to as “2N alcohol”). The conversion rate and optical purity of the product are given in Table 1, below.
