Versuchsvorschrift

A solution of 5-ethyl-3-(trifluoromethyl)-1H-pyrazole-1-acetic acid (170 mg, 0.76 mmol) (i.e. the product of Example 16, Step C) in ethyl acetate (5.0 mL) was treated with 1-propanephosphonic acid cyclic anhydride (50% solution in ethyl acetate, 1.0 mL, 1.6 mmol) and the reaction mixture was stirred at room temperature for 30 minutes. The reaction mixture was added to a stirred suspension of N-methyl-2-(4-piperidinyl)-N-[(1R)-1,2,3,4-tetrahydro-1-naphthalenyl]-4-thiazolecarboxamide monohydrochloride (i.e. the product of Example 6 Step C) (219 mg, 0.56 mmol), triethylamine (0.5 mL, 3.75 mmol) in ethyl acetate (5 mL). The reaction mixture was then stirred at room temperature for 12 h. The resulting suspension was concentrated in vacuo and purified by silica gel MPLC using ethyl acetate/hexanes as eluant to give 200 mg of the title product, a compound of the present invention as an oil.
