LiAl4 (227 mg, 5.97 mmol) was slurried in a mixture of THF (5 mL) and dioxane (5 mL) and cooled to 0° C. under an atmosphere of N2. 4-(tert-Butoxycarbonylamino-methyl)-benzoic acid was dissolved in a mixture of THF (5 mL) and dioxane (5 mL) and added to the chilled solution drop-wise over 15 min. The reaction mixture was allowed to warm to r.t and stirred for 16 h. Water (1 mL) was added to the reaction mixture which was then filtered through celite. The filtrate was evaporated to dryness and the residue partitioned between EtOAc (25 mL) and water (25 mL). The aqueous layer was extracted with EtOAC (2×25 mL), the organic layers combined, dried (Na2SO4) and evaporated to dryness to afford the desired product (460 mg, 100%). m/z 260 [M++Na]+
