실험 절차

A mixture of 200 mg (1.4 mmol) of the compound from Example 11A, 262 mg (1.7 mmol) of 4,4-difluoropiperidine hydrochloride and 289 μl (215 mg, 1.7 mmol) of N-ethyl-N-(propan-2-yl)propane-2-amine in 3 ml of water is stirred at 100° C. for 16 h. Following the addition of 53 μl (79 mg, 0.7 mmol) of trifluoroacetic acid and 325 mg (1.4 mmol) of the compound from Example 7A, the reaction mixture is stirred at 100° C. for 16 h. The precipitated solid is filtered off and washed first with water and then with diethyl ether. The product is dried under reduced pressure. Yield: 34 mg (7% of theory)
