実験手順

A mixture of 1-(1,1-dimethylethyl) 4-[4-carboxy-2-thiazolyl]-1-piperidinecarboxylate (i.e. the product of Example 1, Step B) (3.84 g, 12.29 mmol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (2.36 g, 12.29 mmol) and triethylamine (2.3 mL, 16.76 mmol) in 50 mL dichloromethane was stirred for 15 minutes at room temperature. (1R)-1,2,3,4-Tetrahydro-N-methyl-1-naphthalenamine (i.e. the product of Example 6, Step A) (2.18 g, 13.5 mmol) was added and the reaction mixture was stirred for 16 h. The reaction mixture was diluted with 20 mL of dichloromethane, washed with 1 N aqueous hydrochloric acid, water, saturated aqueous sodium bicarbonate solution, water and brine, dried over MgSO4 and concentrated under reduced pressure. The residue was purified by silica gel chromatography using 20% to 100% of ethyl acetate in hexanes to give 2.4 g of the title compound as an oil.
