A solution of 3-(2-methylpyrrolidin-1-yl)propan-1-ol (1.9 g, 13.4 mmol) in dry DMF (40 ml) is treated at 0° C. with sodium hydride (60% dispersion in mineral oil, 536 mg, 13.4 mmol) and stirred 15 minutes at 0° C. Then, a solution of [2-(6-chloropyridin-3-yl)-4-methyl-4,5-dihydro-1,3-oxazol-4-yl]methanol ax55 (1.8 g, 7.9 mmol) in dry DMF (40 ml) is added dropwise over 15 minutes and the resulting mixture is stirred at room temperature for 1 day. The mixture is then poured into ice-cold water (250 ml) and extracted with ethyl acetate (4×50 ml). The organic layers are combined, dried over sodium sulfate and concentrated. The residue is dried under high-vacuum with heating to leave a solid. This solid is taken up in ethyl acetate, washed with brine and filtered. After phase separation, the aqueous layer is extracted twice with ethyl acetate, the combined organic phases are washed three times with water, dried over magnesium sulfate and concentrated to afford 1.4 g of 80% pure (4-methyl-2-{6-[3-(2-methylpyrrolidin-1-yl)propoxy]pyridin-3-yl}-4,5-dihydro-1,3-oxazol-4-yl)methanol ax56.
