Reaction Conditions

Reaction Steps

NaH (24 mg, 0.6 mmol) was added to solution of 2-((tert-butyldimethylsilyl)oxy)ethanol (70 mg, 0.4 mmol) in DMF (1.0 mL) at 0° C., and the reaction was stirred at 0° C. for 30 minutes. A solution of 6-chloro-4-(5-chloro-2-fluoropyridin-3-yl)-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine (racemic, Example 18.1, Step 1; 100 mg, 0.2 mmol) was added, and the reaction was stirred at 0° C. for 30 minutes. The reaction was quenched by adding saturated aqueous NH4Cl solution and extracted using EtOAc. The organic layer was washed with brine, dried over Na2SO4, filtered and concentrated. Purification of the residue on a silica gel column with 0 to 50% EtOAc/hexane afforded 4-[2-(2-{[tert-butyl(dimethyl)silyl]oxy}ethoxy)-5-chloropyridin-3-yl]-6-chloro-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine (racemic). MS APCI calc'd. for C34H49Cl2N5O3Si [M+H]+ 674. found 674.
