Procedure
178 mg (0.5 mmol) of 2-chloro-3-[5-(cyanomethyl)-4,5-dihydro-1,2-oxazol-3-yl]-4-(ethylsulfonyl)benzoic acid and 90 mg (0.65 mmol) of N-allyl-1-methyl-1H-tetrazol-5-amine are stirred in 3 ml of pyridine at room temperature (RT) for 1 h, and then a solution of 86 mg (0.675 mmol) of oxalyl chloride in 2 ml of dichloroethane is added. Subsequently, the mixture is stirred at 75° C. for 4 h. After cooling to RT, 0.5 ml of water is added. Then the mixture is stirred at RT for 30 min. The reaction solution is filtered and concentrated. The residue is purified by means of preparative HPLC (acetonitrile/water). Yield: 19 mg (8%).
