Reaction Steps

Add NaH (60% oil suspension, 30 mg, 0.750 mmol) to a solution of [5-(5-cyanopyridin-2-yloxy)-1,2,3,4-tetrahydro-naphthalen-1-ylmethyl]-carbamic acid tert-butyl ester (Intermediate 22, 189 mg, 0.500 mmol) and DMF (5 ml) stirring at ambient temperature under nitrogen. After 20 minutes, add 1-bromo-4-methylpentane (247 mg, 1.50 mmol) and beat the mixture at 60° C. overnight. After cooling, pour the mixture into water and extract with EtOAc (2×). Wash the extract with water and brine before drying ((MgSO4) and concentrating. Purify on silica gel (20% EtOAc/Hexane) to obtain 111 mg of [5-(5-cyano-pyridin-2-yloxy)-1,2,3,4-tetrahydro-naphthalen-1-ylmethyl]-(4-methyl-pentyl)carbamic acid tert-butyl ester as a colorless glass.
