実験手順

(5-Methylthiophen-2-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 9, step b) (0.53 g) was added to a solution of 2,3-difluoro-5-(2-hydroxyethyl)benzaldehyde (example 32, step b) (0.25 g) and acetic acid (0.08 mL) in methanol (5 mL). The reaction was stirred for 30 min and cooled in an ice bath. Sodium cyanoborohydride (0.13 g) was then added, the mixture allowed to warm to RT and stirred for 18 h. The reaction was concentrated in vacuo. Purification was by silica gel chromatography eluting with 99:1:0.1 to 97:3:0.3 DCM:methanol:‘880’ aqueous ammonia gradient. The fractions containing product were combined and evaporated in vacuo to give the subtitled compound as a gum. Yield 0.08 g.
