반응 단계

Methylmagnesium bromide (190 mL of a 1.4 M solution in toluene/THF 3:1, 270 mmol) was added over 35 min to a solution of quinoline-6-carboxylic acid methoxy-methyl-amide (Stage 1.5, 26 g, 120 mmol) in THF at 0° C. under nitrogen. The RM was stirred for 30 min at 0° C. and then allowed to warm up to rt. The RM was quenched with 1 M HCl and the THF removed under reduced pressure. The residue was taken up in EtOAc and the organic layer separated, dried and concentrated to give the title compound as a yellow solid (tR 1.0 min (conditions 1), MH+=172).
