반응 단계

1-Cyano-1-methylethyl chloroformate (0.4 g; 1.65 mmol; from step (a) above) was added to a stirred solution of 4-[3-(3,7-diazabicyclo[3.3.1]non-3-yl)-2-hydroxypropoxy]benzonitrile (0.5 g; 1.65 mmol; see Example G above) and K2CO3 (0.7 g) in MeCN (25 mL). The reaction mixture was stirred at 40° C. for 2 h. The salts were filtered off and the filtrate was concentrated and subjected to column chromatography (DCM:MeOH; 19:1) to give the title compound in a 59% yield.
