Reaction Steps

4N HCl solution in dioxane (44 eq.) was added at RT to D1. The resulting 0.1 M solution obtained was stirred for 1 h at RT, then the solvent was removed under reduced pressure. The residue was co-evaporated with toluene (×3) and it was used as such in next step without further purification. MS (ES+) C15H17N3O2 requires 271, found: 272 (M+H)+.
