Reaction Steps
To a solution of (RS)-1-amino-3-{4-[5-(2-chloro-6-methyl-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-2,6-dimethyl-phenoxy}-propan-2-ol (134 mg, 0.345 mmol) in DCM (10 mL), glycolic acid (54 mg, 0.707 mmol) and DIPEA (132 mg, 1.02 mmol) is added. The mixture is cooled to 0° C. and TBTU (134 mg, 0.416 mmol) is added. The mixture is stirred at 0° C. for 1 h, then at rt for 16 h before it is diluted with EA (250 mL), washed with 1 N aq. NaOH solution (3×25 mL), 1 N aq. KHSO4 (25 mL) and brine (25 mL), dried over Na2SO4, filtered and concentrated. The crude product is purified by prep. HPLC to give N-((RS)-3-{4-[5-(2-chloro-6-methyl-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-2,6-dimethyl-phenoxy}-2-hydroxy-propyl)-2-hydroxy-acetamide (23 mg) as a colourless resin; LC-MS: tR=0.91 min, [M+1]+=447.44.
