Reaction Steps

A solution of (1R,2R,4R) and (1S,2S,4S)-4-(4-bromo-2-trifluoromethyl-benzenesulfonyl)-2-methoxy-cyclopentanecarboxylic acid (1-cyano-cyclopropyl)-amide (50 mg, 0.1009 mmol, example 58), morpholine (22 μl, 0.252 mmol) and 2,6-di-tert-butylpyridine (45.4 μl, 0.202 mmol) in DMA (1 ml) was heated in a sealed tube at 100° C. overnight. Then additional morpholine (8.8 μl, 0.1009 mmol) was added and the solution was stirred another 2 h at 100° C. The mixture was then cooled to room temperature and diluted with water. The pH was adjusted to 10 by addition of saturated Na2CO3 solution and the mixture was extracted 3 times with EtOAc. The combined organic layers were washed two times with Na2CO3 solution (pH 10) and with brine, dried over Na2SO4 and evaporated. The remaining light brown solid was purified by silica gel chromatography (DCM/EtOAc 4:1-1:1) to obtain the title compound (33 mg, 65%) as white foam. MS (EI): 502.2 (M+H)+.
