Reaction Steps

450 mg (1.94 mmol) 5-(4-(4-methoxy-phenyl)-butyl)-2H-tetrazole and 1.5 ml 48% aqueous hydrobromic acid were stirred at 80° C. for 17 h. The reaction mixture was adjusted to pH=4 by addition of conc. NaOH and the aqueous phase discarded. Purification of the undissolved residue by HPLC-MS (methanol/water 7:3, pH=2.3) gave 220 mg (52%) of the title compound.
