Procedure
N-(3-Hydroxy-propyl)-N-quinolin-2-ylmethyl-acetamide (410 mg, 1.5 mmol, EXAMPLE 39a) is dissolved in 20% DMPU in THF (3 mL) and cooled to 0° C. Sodium hydride (60%, 66 mg, 1.65 mmol) is added and the contents are stirred for 10 min. Methyl 2-bromomethyl-6-methyl-benzoate (77%, 365 mg, 1.5 mmol, EXAMPLE 2a) is added. The contents are allowed to come to r.t., and are stirred overnight. The contents are poured into water (100 mL) and extracted with ethyl acetate (3×75 mL). The organic fractions are pooled and washed with water (2×100 mL) and brine (2×100 mL), dried over MgSO4, filtered and reduced under vacuum to an oil. The crude material is purified by flash chromatography (silica, 3% methanol in dichloromethane) to give the title compound. MS (ESI) 435 (M+H)+.
