실험 절차

A solution of 87 mg (0.34 mmol) of (S)-2-[(azepane-1-carbonyl)-amino]-4-methyl-pentanoic acid (Example 1, Step B) and 0.131 mL (1.2 mmol) 4-methylmorpholine was stirred at 25° C. for 30 minutes, after which 136 mg (0.36 mmol) 0-benzotriazol-1-yl-N,N,N′,N′-bis(tetramethylene)uronium hexafluorophosphate in 4 mL dry DMF was added. The resulting solution was cooled in an ice-bath and 150 mg (0.34 mmol) 2-(4-benzyloxy-phenyl)-1-morpholin-4-ylmethyl-ethylamine (Example 3, Step D) was added. The resulting solution was warmed to 25° C. and stirred for 30 minutes. The mixture was then poured into 35 mL diethyl ether, and washed sequentially with 25 mL each of 2.5% aqueous HCl solution, brine, saturated aqueous sodium bicarbonate solution, and finally twice with brine. The mixture was then dried over anhydrous sodium sulfate and concentrated at reduced pressure to give an amber oil that was purified by preparative thin-layer chromatography on a 1000 μm silica gel plate with 50:50:1 ethyl acetate:hexane:methanol as eluant to give 46 mg (24%) of the title compound as a pale amber glass.
