반응 단계
A solution of 2-(2,4-bis-benzyloxy-5-isopropyl-benzoyl)-2,3-dihydro-1H-isoindole-5-carboxylic acid methoxy-methyl-amide (0.226 g, 0.4 mmol) in THF (5 ml) cooled to 0° C., treated with 1M LiAlH4/THF (0.3 ml, 0.3 mmol), stirred 1 hour, further LiAlH4 (0.05 ml) added then stirred for 30 minutes. The reaction was quenched with saturated KHSO4 solution, extracted with EtOAc, dried (MgSO4), filtered and evaporated to give 0.2 g of 2-(2,4-bis-benzyloxy-5-isopropyl-benzoyl)-2,3-dihydro-1H-isoindole-5-carbaldehyde. MS: [M+H]+ 504.
