Reaction Steps

The compound was prepared in an analogous manner as described for intermediate B14A from (R)-5-(5-amino-2-fluorophenyl)-6,6-difluoro-5,7,7-trimethyl-[1,4]oxazepane-3-thione (intermediate A17B) (150 mg, 0.47 mmol) and commercially available 5-cyano-pyridine-2-carboxylic acid [CAS No. 53234-55-2] (105 mg, 0.71 mmol). The compound was obtained as a light brown oil (280 mg, 99%, 75% purity). MS (ISP): m/z=449.2 [(M+H)+].
