Reaction Steps
To a solution of EXAMPLE 336B (1 g) and tert-butyl 4-oxocyclohexylcarbamate (0.877 g) stirred for 24 hours at room temperature in titanium (IV) isopropoxide (2.410 mL), methanol (2 mL) was added followed by careful addition of sodium borohydride (0.311 g). The reaction mixture was quenched with water, extracted with ether, dried and concentrated. The crude product was purified by flash chromotography (silica 80 g, 50%-100% acetone/hexanes) providing the product.
