Sodium hydride 60% in oil (0.11 g, 2.2 eq, 2.82 mmol) is added to a mixture of 3-(2-methyl-1-pyrrolidinyl)-1-propanol (0.31 g, 2.2 eq, 2.18 mmol) in dimethylformamide (15 ml) cooled to 0° C. The mixture is stirred at 22° C. for 20 min, and cooled again to 0° C. 4-{[2-(6-chloropyridin-3-yl)-4-methyl-1,3-thiazol-5-yl]carbonyl}morpholine i99 (0.415 g, 1 eq, 1.28 mmol) is then added to the solution and the mixture is stirred 48 h at room temperature. The solvent is evaporated, and the residue is taken up in ethyl acetate and washed two times with an aqueous solution of sodium hydrogenocarbonate. The organic layer is dried over magnesium sulfate, filtered and concentrated under vacuum. Purification by chromatography over silicagel (eluent: dichloromethane/methanol/ammonia 97/2.7/0.3) affords 0.047 g of 4-[(4-methyl-2-{6-[3-(2-methylpyrrolidin-1-yl)propoxy]pyridin-3-yl}-1,3-thiazol-5-yl)carbonyl]morpholine 147.
