Participants

Reaction Steps

To 1-(propyl-4-pyridinylamino)-1H-indol-5-ol (1.75 g) in 30 ml of tetrahydrofuran was added potassium carbonate (milled, 0.912 g) followed by (S)-(-)-1-methylbenzyl isocyanate (0.97 g), and the reaction was allowed to proceed for one hour. The reaction mixture was filtered and the filtrate concentrated to yield an oil (3.9 g) which was eluted with 5% methanol in dichloromethane (DCM) on a silica gel column via HPLC. The desired fractions were concentrated to yield a solid 2.6 g, m.p. 78°-80° C.
