Versuchsvorschrift

To a solution of 2-isopropyl-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid (synthesized similar to the methods described in sections a) to d) of example X1) (1.86 g, 7.05 mmol) in tetrahydrofuran (60 ml) are added triethylamine (2.9 ml, 21.1 mol) and 0-(7-azabenzotriazol-1-yl)N,N,N′,N′-tetramethyluronium hexafluorophosphate (2.69 g, 7.05 mmol). The mixture is stirred for 15 min at RT, before 1-amino-4,4-dimethylpentan-3-ol (1.02 g, 7.76 mmol) is added and stirring is continued for 18 h. After completion of the reaction, the mixture is diluted with ethyl acetate and 10% aqueous ammonium chloride. The organic layer is separated and washed with saturated sodium hydrogencarbonate solution and brine, dried over magnesium sulphate and evaporated to dryness. The crude product is purified by flash chromatography (silica gel, 30% ethyl acetate/cyclohexane) to yield N-(3-hydroxy-4,4-dimethyl-pentyl)-2-isopropyl-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid amide (example X5) (1.30 g, 3.44 mmol, 49%). [M+H]+378.3.
