Procedure

A mixture of 27.6 mg (0.06 mmol) 4-fluorophenyl (3S,4R)-4-(4-chlorophenyl)-1-(piperidine-4-carbonyl)pyrrolidin-3-yl(methyl)carbamate, 0.52 mL (0.072 mmol) HATU (0.136 M in DMF), 12 mg (0.072 mmol) cyclobutanecarboxylic acid and 46.5 mg (0.36 mmol) DIPEA in 1.5 mL DMF was shaken at room temperature over night. The mixture was subjected to preparative HPLC chromatography on reversed phase eluting with a gradient formed from acetonitrile, water and NEt3. The product containing fractions were evaporated to yield 12.5 mg (39%) of the title compounds as off-white solid. MS m/e: 542.3 [M+H]+.
