Methods for preparing (S)-N-tert-butyl-1,2,3,4-tetrahydro-3-isoquinoline-carboxamide ("tic-c"), and converting tic-c to (S)-decahydroisoquinoline-3-carboxylic acid t-butylamide ("tic-d") are disclosed. The initial step in the formation of tic-c involves the phosgenation of a substituted tetrahydroisoquinoline to form an N-carboxy anhydride. Tic-d is used as an intermediate in the synthesis of known compounds having pharmaceutical activity. |
