Reaction Steps

Triethyl orthoformate (5.29 ml, 31.8 mmol) and 2-(4-aminophenyl) propionic acid (3.26 g, 19.73 mmol) were suspended in acetic acid (50 ml) then added sodium azide (1.924 g, 29.6 mmol). The mixture was refluxed for 3 hours then let stirred at room temperature overnight. The reaction was poured into water (60 ml) and extracted with ethyl acetate (60 ml). The organic layer was separated and dried over MgSO4. The mixture was filtered and concentrated to yield 2-[4-(1H-tetrazol-1yl)phenyl]propanoic acid (4.2 g, 98%). LC-MS (IE, m/z): 219 [M+1]+.
