YieldReaction ConditionsOperation in experiment
74% Step 1: 2-Piperidin-4-yl-thiazole-4-carboxylic acid ethyl ester A mixture of 10 g (41 mmol) 4-thiocarbamoyl-piperidine-1-carboxylic acid tert-butyl ester (commercially available) and 7.98 g (41 mmol) ethyl bromopyruvate (commercially available) in 120 ml ethanol was stirred at 70 C. for 90 min. The mixture was evaporated to dryness, Na2CO3 aq. was added and the residue was extracted with ethyl acetate. The organic phases were washed with NaCl aq., dried with MgSO4 and evaporated to dryness. The residue was purified on silica eluding with DCM/MeOH/25% NH3 in water 100/20/1 to yield after evaporation of the product fractions 7.28 g (74%) of the title compound as light brown solid.

98% Example 5: This example illustrates the preparation of N-(2-{1-[2-(2,5-Dimethyl-phenyl)- acetyl]-piperidin-4-yl}-thiazol-4-yl)-2-phenyl-propionamide (Compound No. l.g.141 ) a) Preparation of 2-{1-[2-(2,5-dimethyl-phenyl)-acetyl]-piperidin-4-yl}-thiazole-4-carboxylic acid ethyl esterTo a solution of <strong>[13612-34-5]2,5-dimethylphenylacetic acid</strong> (5.45 g, 27.4 mmol) in DMF (80 mL) is added diisopropylethylamine (85.4 mL, 411.32 mmol), followed by O-(benzotriazol-i-yl)- N,N,N',N'-tetramethyluronium tetrafluoroborate (12.8 g, 32.9 mmol) at 0 0C. After stirring 15 min at RT, 2-piperidin-4-yl-thiazole-4-carboxylic acid ethyl ester (6.59 g, 27.4 mmol) is added to the reaction mixture. After stirring overnight at RT, solvent is evaporated and the resulting yellow oil is dissolved in ethylacetate (500 mL), washed with aqueous saturated sodium bicarbonate solution (500 mL) and the aqueous phase is re-extracted with ethylacetate (100 mL). The combined organic layers are washed with 0.5M HCI solution (400 mL) and brine (400 mL), dried over sodium sulfate, filtered, and evaporated under reduced pressure to give 2-{1-[2-(2,5-dimethyl-phenyl)-acetyl]-piperidin-4-yl}-thiazole-4- carboxylic acid ethyl ester (10.46 g, 98 percent), which can be used in the next step without further purification. 1H-NMR (400 MHz, CDCI3): delta = 1.41 (t, 3H), 1.52-1.82 (m, 2H), 2.10- 2.22 (m, 2H), 2.25 (s, 3H), 2.30 (s, 3H), 2.73-2.86 (m, 1 H), 3.08-3.22 (m, 1 H), 3.29-3.40 (m, 1 H), 3.68 (s, 2H), 3.8-3.95 (m, 1 H), 4.38-4.42 (q, 2H), 4.73-4.88 (m, 1 H), 6.96 (s, 1 H), 6.98- 7.01 (d, 1 H), 7.08 (d, 1 H), 8.10 (s, 1 H).
