Reaction Steps

The (S)-2-(tert-butoxycarbonylamino)-3-((R)-4-oxaspiro[2.5]oct-6-yl)propyl 4-methylbenzenesulfonate was dissolved in 100 mL of 33% NH2Me in ethanol. The mixture was heated to 50° C. for 3 hr. After this time LC/MS analysis shows formation of the desired amine. The solution was evaporated and the residue taken up in EtOAc, washed with 10% K2CO3, brine, dried over Na2SO4, filtered and evaporated. The tert-butyl (S)-1-((R)-4-oxaspiro[2.5]oct-6-yl)-3-(methylamino)propan-2-ylcarbamate was used directly in the next step with no further purification. MS ESI +ve m/z 301 (M+1).
