Reaction Steps

1.1 g (4.8 mmol) 2-methyl-1,2,3,4-tetrahydroisoquinoline-6-carboxylic acid (as hydrochloride) are dissolved in 12 ml DMF, mixed with 2.1 ml (19.3 mmol) NMM and 1.8 g (4.8 mmol) HATU and stirred for five minutes at RT. Then 0.9 g (4.8 mmol) tert. Butyl (R)-pyrrolidin-3-yl-carbamate are added and the mixture is stirred for 16 hours. Then the mixture is poured onto water and extracted with DCM. The organic phase is separated using a phase separation cartridge and evaporated to dryness i. vac. The residue is purified by flash chromatography on silica gel (eluant DCM/MeOH 9:1 to 8:2).
