実験手順

A bi-phasic mixture of Example A4 (1.00 g, 2.142 mmol) in EtOAc (25 mL) and satd. NaHCO3 (25 mL) was treated with isopropenyl chloroformate (516 mg, 4.28 mmol) and stirred vigorously at RT for 3 h. Hexane (10 mL) was added and the resulting solid collected via filtration and dried. The layers of the filtrate were separated, the organic layer washed with brine, dried over Na2SO4, concentrated to dryness and combined with the above-isolated solid to afford prop-1-en-2-yl (4-chloro-5-(1-ethyl-7-((4-methoxybenzyl)(methyl)amino)-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)carbamate (1.168 g, 98% yield). MS (ESI) m/z: 551.2 [M+H]+.
