Procedure

To a solution of 3-(2H-tetrazol-5-yl)-pyridin-2-ylamine (100 mg) described in Manufacturing Example 5-1, 4-benzyloxybenzyl chloride (172 mg), sodium iodide (111 mg), and DMF (3 mL) was added NaH (18 mg), which was stirred for 40 minutes at 60° C. Water was added to the reaction solution, which was then extracted with ethyl acetate. The organic layer was concentrated under a reduced pressure, and the residue was purified by NH silica gel column chromatography (hexane:ethyl acetate=4:1, then 2:1, then 1:1). Ethyl acetate was added to the resulting residue, and the solids were filtered off to obtain the titled compound (38 mg).
