Procedure
A mixture of compound 58 (0.155 g, 0.58 mmoles) and methyl 2-(aminomethyl)pyridine-4-carboxylate dihydrochloride (0.139 g, 0.58 mmoles) (see WO2003070732, example 6, step 2 for preparation, which is incorporated by reference in its entirety) in dichloromethane (20 ml) was treated with N,N,N′,N′-tetramethyl-O-(1H-benzotriazol-1-yl)uranium hexafluorophosphate (0.264 g, 0.69 mmoles) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.133 g, 0.69 mmoles) and N-methylmorpholine (0.255 ml, 2.32 mmoles) then stirred at ambient temperature under a nitrogen atmosphere for 18 h. The mixture was washed with water (2×20 ml) and saturated brine (20 ml) then separated and dried over sodium sulphate, filtered and evaporated to dryness. The residue was chromatographed on silica gel eluting with an ethyl acetate/isohexane gradient. This gave the title compound as a colorless oil (0.184 g 76%).
