Liquid ammonia (ca. 30 ml) was added to a solution of (2R)-2-{[(benzyloxy)carbonyl]amino}-5-[(methylsulfonyl)oxy]pentyl methanesulfonate (1 g) in THF (15 ml) at −78° C. in a bomb reaction vessel and then the resultant mixture was allowed to reach room temperature. After 46 h, the solution was concentrated under reduced pressure to give an off-white solid which was purified using SPE (silica, eluting with methanol, methanol:aqueous ammonia 95:5, 9:1) to give the title compound (0.587 g) as an off white solid.
