실험 절차

2-[(3S)-3-Aminopyrrolidin-1-yl]-6-chloro-N-[(1-hydroxycycloheptyl)methyl]-quinoline-5-carboxamide (17.6 g) was suspended in dichloromethane (300 ml) and molecular sieves (17.6 g) were added under a nitrogen atmosphere. [[(1,1-dimethylethyl)-dimethylsilyl]-oxy]acetaldehyde (7.2 ml) was added dropwise with stirring over 5 minutes and the mixture was stirred at room temperature for 6 hours. Sodium triacetoxyborohydride (17.9 g) was added in one portion and the mixture was stirred at room temperature for a further 17 hours before water (10 ml) was added, the mixture was stirred at room temperature for 30 minutes, concentrated onto silica in vacuo and purified by flash column chromatography (SiO2, 1:2:97-1:8:91 7M NH3 in methanol:methanol:dichloromethane as gradient elution) to afford the subtitle product as a colourless solid (16.0 g). Impure fractions (4.1 g) were repurified by flash column chromatography (SiO2, 1:2:97-1:8:91 7M NH3 in methanol:methanol:dichloromethane as gradient elution) to afford a second crop of the subtitle product (2.8 g).
