Procedure

A bi-phasic mixture of Example A3 (250 mg, 0.710 mmol) in EtOAc (10 mL) and satd. NaHCO3 (15 mL) was treated with isopropenyl chloroformate 9120 mg, 0.984 mmol) and stirred at RT for 2 h. The layers were separated, the organic layer washed with water, then brine, dried over Na2SO4 and concentrated to dryness to afford prop-1-en-2-yl (4-chloro-5-(7-chloro-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2-fluorophenyl)carbamate (292 mg, 94% yield). MS (ESI) m/z: 436.0 [M+H]+.
