Procedure

To an ice-cooled solution of (2S,4S)-2-(4-cyclobutyl-[1,4]diazepane-1-carbonyl)-4-(4-fluoro-phenoxy)-pyrrolidine (29 mg, 0.08 mmol) in THF (0.8 mL) with Et3N (60 μL, 0.4 mmol) was added methanesulfonyl chloride (19 μL, 0.24 mmol). The reaction mixture was allowed to warm to rt and was stirred for 18 h. The mixture was diluted with satd. aq. NaHCO3 and extracted with CH2Cl2 (3×). The combined organic layers were dried and concentrated. Purification by FCC provided the desired product (31 mg, 87%). MS (ESI): mass calcd. for C21H30FN3O4S, 439.19; m/z found, 440.5 [M+H]+. 1H NMR (CDCl3): 7.00-6.94 (m, 2H), 6.83-6.78 (m, 2H), 4.94-4.89 (m, 1H), 4.86 (ddd, J=8.8, 4.4, 4.4 Hz, 1H), 4.10-4.03 (m, 1H), 3.78-3.40 (m, 5H), 3.08 (d, J=4.0 Hz, 3H), 2.84 (dd, J=16.2, 7.8 Hz, 1H), 2.75-2.66 (m, 1H), 2.57-2.26 (m, 4H), 2.25-2.14 (m, 1H), 2.07-1.97 (m, 2H), 1.97-1.71 (m, 4H), 1.69-1.55 (m, 2H).
