実験手順

HATU (0.183 g) was added in one portion to a stirred solution at 0° C. of 5-isopropylthiophene-3-carboxylic acid (0.063 g) and 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)-2-fluorophenyl)ethanol (example 67, step f) (0.114 g) and triethylamine (0.155 mL) in DMF (5 mL). The reaction mixture was stirred at room temperature for 2 hours. The mixture was partitioned between ethyl acetate and brine, the organic layer was washed twice with brine, dried over sodium sulphate, filtered and the solvent evaporated under reduced pressure. The crude product was purified by flash silica chromatography using 2.5% methanol in dichloromethane with 1% triethylamine as solvent. Pure fractions were evaporated to dryness to afford the subtitled compound. Yield 0.100 g.
