Procedure

A solution of tert-Butoxycarbonylamino-acetic acid (1.88 g, 10.7 mmol) in dichloromethane (15 ml) is treated with triethylamine (1.5 ml, 10.7 mmol) and [Dimethylamino-[1,2,3]-triazolo-[4,5-b]pyridin-3-yloxy)-methylene]-dimethyl-ammonium hexafluoro phosphate (4.06 g, 10.7 mmol) and stirred for 5 minutes. To the reaction mixture is added a solution of C-[1-(3,4-Dichloro-benzyl)-azetidin-3-yl]-methylamine (2.64 g, 10.7 mmol) in dichloromethane (15 ml) with stirring for a further 3 hours. The reaction mixture is partitioned between dichloromethane and saturated sodium bicarbonate solution, the organic phase is washed with brine, dried over magnesium sulphate and evaporated. The crude product is purified by chromatography over flash silica eluting with 7% methanol in dichloromethane to afford the title compound.
