Reaction Conditions

Reaction Steps

6-aminohexanoic acid (904 mg, 6.89 mmol) and NaOH (415 mg, 10.34 mmol) were dissolved in H2O (30 mL) and cooled to 0-5° C. Methanesulfonyl chloride (0.586 mL, 7.58 mmol) was added dropwise and the reaction mixture stirred for 2 h, then warmed to ambient temperature and stirred for an additional 2 h. The mixture was acidified with HCl (1 N) and extracted with EtOAc (3×15 mL). The extracts were combined, washed with H2O, then brine, dried over MgSO4, and filtered. Evaporation under reduced pressure gave 69 as a white crystalline solid (207 mg, 0.99 mmol, 14%). 1H-NMR (400 MHz, DMSO-d6) δ 11.95 (s, 1H), 6.91 (t, 1H), 2.90 (dt, 2H), 2.87 (s, 3H), 2.20 (t, 2H), 2.48 (m, 2H), 2.43 (m, 2H), 1.27 (m, 2H).
