Isoamyl nitrite (170 μL, 1.3 mmol) was added dropwise to a cooled (water ice bath) solution of 2-(R)-(2-acetoxymethyl-4-amino-3-methyl-benzyl)-succinic acid diethyl ester in 5% acetic acid—chloroform (5 mL). Mixture was stirred at 0° C. for 1.5 hours. Mixture was diluted with dichloromethane (20 mL) and then washed with saturated aqueous sodium bicarbonate (2×20 mL). Organic was dried (magnesium sulfate), filtered and concentrated in vacuo. Title compound was obtained as amber oil in 99% yield. MS m/e (M+H)+=377.1.
