Vorschrift

To 1-(benzo[d][1,3]dioxol-5-yl)-N-(3′-chloro-4′-cyano-6-methylbiphenyl-3-yl)-cyclopropanecarboxamide was added ammonium chloride (0.13 g, 2.4 mmol), sodium azide (0.156 g, 2.40 mmol) and 1 mL of DMF. The mixture was heated at 110° C. in a microwave reactor for 10 minutes. After cooling, the mixture was filtered and purified by preparative HPLC to provide 1-(benzo[d][1,3]dioxol-5-yl)-N-(3′-chloro-6-methyl-4′-(2H-tetrazol-5-yl)biphenyl-3-yl)cyclopropanecarboxamide (8.6 mg, 9%). ESI-MS m/z calc. 473.1. found 474.3 (M+1)+; retention time 1.86 minutes.
