Participants

Reaction Steps

46.3 mg (1.84 mmol) 95% sodium hydride were given at 0° C. to a solution of 200 mg (0.916 mmol) 4-(4-tetrazol-5-yl-butyl)-phenol in 5.0 ml N,N-dimethylformamide and stirred for 15 min. 317 mg (0.916 mmol) 4-chloromethyl-2-[2-(4-pentafluorosulfanyl-phenyl)-vinyl]-oxazole were added and stirring continued at 25° C. for 2 h. The reaction mixture was neutralized with HCl, poured into water and the resulting precipitate was purified by HPLC-MS, treated with diethyl ether, filtered and dried to yield 106 mg (22%) of the title compound.
