Participants

Reaction Steps

To a solution of p-azidomethylbenzoic acid (1.063 g, 6.00 mmol) in CH2Cl2 (60 ml) at room temperature were added dropwise thionyl chloride (1 ml, excess) and DMF (5 drops). The mixture was stirred at room temperature for 2.5 h and evaporated, yielding 1.13 g of title compound as a light yellow oil: 1Hmr (CDCl3) δ: 4.48 (2H, s, --CH2N3), 7.38-7.52-8.07-8.22 ppm (4H, A2 'B2 ', aromatic Hs); ir (neat) νmax : 2090 (--N3) and 1750 cm-1 (br. --COCl). This material was used in the next step without further purification.
