Diisopropylethylamine → (5S)-5-({[6-(2-Cyclopropylpyrimidin-5-yl)-3,4-dihydroisoquinolin-2(1H)-yl]sulfonyl}methyl)-5-methylimidazolidine-2,4-dione

Participants

Reaction Steps

[(4S)-4-Methyl-2,5-dioxoimidazolidin-4-yl]methanesulfonyl chloride (0.020 g, 0.087 mmol) in anhydrous THF (0.40 mL) was added dropwise to a stirred solution of 6-[2-(cyclopropyl)pyrimidin-5-yl]-1,2,3,4-tetrahydroisoquinoline (0.023 g, 0.091 mmol), DIPEA (0.022 mL, 0.13 mmol) and dry THF (0.50 mL) at RT. After the addition was complete, the solution was stirred at RT for 2 h and then taken up in water-brine and extracted twice with EtOAc. The combined organic phases were washed with brine, dried, filtered and concentrated to give a crude product. Purification by preparative HPLC afforded 0.021 g (50%) of the title compound as a white solid.
