实验步骤: 2-Bromo-6-(bromomethyl)pyridine (Example 190, Step 1) (150 mg, 0.60 mmol), morpholine-3-carboxamide hydrochloride (100 mg, 0.560 mmol) and potassium carbonate (207 mg, 1.50 mmol) were taken up in DMF (3 mL) and the reaction was maintained at room temperature overnight. Water was then added and the mixture was extracted with EtOAc (2×). The combined organic extracts were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo to give the title compound as an orange oil. the mixture was extracted with EtOAc (2×) The combined organic extracts were washed with brine dried over MgSO4 filtered concentrated in vacuo

实验步骤: 2.9 g of molecular sieve 3A, 4.3 g (72 mmol) of acetic acid, 7.6 g (43.2 mmol) of 2(1-ethoxy-cyclopropyl)oxy]trimethylsilane and 4.4 g (31.7 mmol) of sodium cyanoborohydride are added successively to 1.2 g (7.2 mmol) of morpholine-3-carboxylic acid amide hydrochloride (WO2005026156 Hennequin L. F. A. et al.) in solution in methanol (36 ml). The reaction mixture is heated at 70° C. for 3.5 hours, then cooled to room temperature and filtered. The filtrate is concentrated under reduced pressure, then the residue is taken up in dichloromethane (200 ml) and washed 3 times with an aqueous solution of NaOH (1N) (100 ml). The organic phase is dried over Na2SO4, filtered and then concentrated under reduced pressure. 0.58 g of product is obtained, in the form of a white powder. Yield 47%. Melting point 116° C. MH+: 171 (Tr: 1.03 min, condition 2). cooled to room temperature filtered The filtrate is concentrated under reduced pressure washed 3 times with an aqueous solution of NaOH (1N) (100 ml) The organic phase is dried over Na2SO4 filtered concentrated under reduced pressure
