Procedure

A mixture of 2-[1-[(2,5-dimethylphenyl)acetyl]-4-piperidinyl]-4-oxazolecarboxylic acid (i.e. the product of Example 9, Step F) (245 mg, 0.72 mmol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (153 mg, 80 mmol) and 4-methylmorpholine (88 μL) in 3 mL of dichloromethane were stirred at room temperature for 15 minutes. (α,R)-α-Ethyl-N-methylbenzenemethanamine (i.e. the product of Example 1, Step C) (0.80 mmol, 119 mg) was added and the reaction mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with dichloromethane, washed with 1 N aqueous hydrochloric acid and water, dried over MgSO4 and concentrated under reduced pressure. The products were purified by silica gel chromatography using 50-100% ethyl acetate in hexanes as eluant to give 90 mg of the title product, a compound of the present invention as an oil.
