Procedure

((S)-3-chloro-2-hydroxypropyl)-methylcarbamic acid tert-butyl ester (2.23 g, 10 mmol) was dissolved in THF (30 mL), and then an aqueous sodium hydroxide solution (0.48 g in 10 mL water) was added. The mixture was stirred for 2 h. The mixture was then concentrated under reduced pressure to remove most of the THF, and the remaining aqueous solution was extracted into ethyl acetate, washing with water. The product was dried over sodium sulfate, filtered and concentrated under reduced pressure to give the title intermediate as an oil (1.6 g). (m/z): [M+Na]+ calcd for C9H17NO3, 210.10; found 210.1. 1H—NMR (DMSO d6, 299.96 MHz): δ (ppm) 1.32-1.42 (s, 9H), 2.69-2.73 (m, 1H), 2.75-2.85 (s, 3H), 2.95-3.05 (br s, 1H), 3.10-3.15 (dm, 1H), 3.16-3.21 (d, 1H), 3.37-3.51 (m, 2H).
