Reaction Steps

A vial containing a mixture of (2S,3S)-2-(4-cyclobutyl-[1,4]diazepane-1-carbonyl)-3-methanesulfonyloxy-pyrrolidine-1-carboxylic acid tert-butyl ester (106.0 mg, 0.24 mmol), 3-fluorophenol (29.3 mg, 0.26 mmol), and K2CO3 (39.5 mg) in DMF (2.5 mL) was capped and heated for 60 h at 90° C. The mixture was cooled to rt and filtered. The filtrate was concentrated and the residue was purified by FCC to afford the title compound (17 mg, 15%). MS (ESI): mass calcd. for C25H36FN3O4, 461.57; m/z found, 462.3 [M+H]+. 1H NMR (CDCl3): 7.25-7.19 (m, 1H), 6.74-6.64 (m, 2H), 6.64-6.57 (m, 1H), 5.09-4.70 (m, 2H), 3.81-3.49 (m, 6H), 2.90-2.76 (m, 1H), 2.59-2.29 (m, 5H), 2.15-1.72 (m, 7H), 1.64-1.53 (m, 2H), 1.49-1.41 (m, 9H).
