(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentanamine → N-[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}-methyl)cyclopentyl]-6-chloro-N'-[(1S)-3,3-dimethyl-2,3-dihydro-1H-inden-1-yl]-1,3,5-triazine-2,4-diamine

Reaction Steps

To a solution of (1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentanamine (0.200 g, 0.556 mmol), TEA (0.21 mL, 1.50 mmol) in THF (0.80 mL) was added 4,6-dichloro-N-[(1S)-3,3-dimethyl-2,3-dihydro-1H-inden-1-yl]-1,3,5-triazin-2-amine (0.160 g, 0.500 mol). The reaction was stirred for 3.5 h then concentrated in vacuo. The residue was purified by preparative TLC (10% EtOAc/hexanes) followed by DCM. The relevant band was cut and washed using acetone, filtered, and concentrated in vacuo to afford the title compound (0.228 g, 71%). LC/MS: Rt=2.77 min, ES+ 633 (FA standard).
