Participants

Reaction Steps

To 2-(tert-butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-6-carboxylic acid (0.2 g, 0.721 mmol) and aniline (0.066 mL, 0.721 mmol) and TEA (0.251 mL, 1.803 mmol) in EtOAc (5 mL) was added a 50% solution of T3P in DMF (0.408 mL, 1.442 mmol). After 24 h, the reaction was partitioned with dilute HCl (10 mL) and EtOAc (20 mL). The organic layer was washed with brine (10 mL) and dried (MgSO4). Purification by silica gel chromatography afforded 0.238 g of Intermediate 19A. MS (ESI) m/z: 352.9 (M+H)+.
