Reaction Steps

Potassium t-butoxide (1.0M in THF; 1.33 ml, 1.33 mmol) was added to a solution of 5-chloro-N-(2-cyano-5,6,7,8,9,10-hexahydro-6,9-methanobenzo[a][8]annulen-11-yl)thiophene-2-sulfonamide (Example 176) (350 mg, 0.89 mmol) in THF (10 ml) and stirred for 20 mins. Chloromethyl methyl ether (108 μl, 1.42 mmol) was added and the reaction stirred overnight at RT. More reagents were added as necessary until the reaction was complete by NMR. The reaction mixture was poured into water (25 ml) and extracted with ethyl acetate (2×25 ml). The combined organic layers were washed with brine, dried over MgSO4 and evaporated to give 5-chloro-N-(2-cyano-5,6,7,8,9,10-hexahydro-6,9-methanobenzo[a][8]annulen-11-yl)-N-(methoxymethyl)thiophene-2-sulfonamide (388 mg, quant.).
