Procedure

HATU (0.181 g) was added in one portion to a stirred solution at 0° C. of benzo[b]thiophene-5-carboxylic acid (0.065 g) and 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)-2-fluorophenyl)ethanol (example 67, step f) (0.113 g) and triethylamine (0.153 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 to afford the subtitled compound. Yield 0.160 g.
