Methanol → 2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-9-(1-methyl-5-(1-methylpyrrolidin-3-yl)-1H-pyrazol-4-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine

Reaction Steps

A mixture of 1-tert-butyl-6-(1-methyl-4-{4-[3-methyl-1-(propan-2-yl)-1H-1,2,4-triazol-5-yl]-9-oxa-3,6-diazatricyclo[8.4.0.02,6]tetradeca-1(14),2,4,10,12-pentaen-12-yl}-1H-pyrazol-5-yl)-λ3,3-oxazepan-2-one (150 mg, 0.269 mmol) and LiAlH4 (51 mg, 1.3 mmol) in THF (5 mL) was refluxed for 1 hr. MeOH was added to quench reaction, The solid was filtered off and the filtrate was evaporated to afford the crude product, which was purified by reverse phase Combiflash eluting with a 0-70% gradient of CH3CN in 0.3% NH4HCO3 to give racemic 240 (65 mg, 51% yield), which was separated by chiral SFC (Cellulose-2 column, 10% MeOH (0.1% DEA) isocratic) to give: 22.5 mg of one enantiomer and 35.5 mg of the other (46% total yield). LCMS (ESI): RT=4.79 min, m/z: 473.4 [M+H+]. 1H-NMR (500 MHz, DMSO-d6) δ 8.41 (d, J=8.5 Hz, 1H), 7.90 (s, 1H), 7.52 (s, 1H), 7.12 (dd, J=1.5 Hz, J=8.5 Hz, 1H), 6.99 (s, 1H), 5.77 (t, J=7.0 Hz, J=13.5 Hz, 1H), 4.53 (s, 4H), 3.97 (s, 3H), 3.74 (s, 1H), 2.80-2.74 (m, 2H), 2.65 (t, J=9.5 Hz, J=18.5 Hz, 1H), 2.49-2.46 (m, 1H), 2.30 (s, 3H), 2.26 (s, 3H), 2.19-2.17 (m, 1H), 1.96-1.93 (m, 1H), 1.46 (s, 6H)
