Ozone was bubbled into a solution of methyl [allyl(tert-butoxycarbonyl)amino]acetate (3.6 g, 16 mmol) in DCM at −78° C. until it turned pale blue. Nitrogen was then bubbled into the solution to remove excess ozone. When the blue color was gone, 6-amino-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (2.7 g, 16 mmol) and sodium triacetoxyborohydride (20 g, 95 mmol) was added to the reaction, and the mixture was allowed to warm to RT. The reaction was diluted with DCM, washed with aqueous sodium bicarbonate and brine, dried over magnesium sulfate, and purified by preparative TLC to afford the title compound. LC-MS (IE, m/z): 256 [M−Boc+1]+.
