実験手順

To a solution of N-(2-(2-amino-3-benzyl-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide (40.5 mg, 0.095 mmol; see example 193) in dry dichloromethane (2 ml) containing diisoproylamine (0.025 ml, 0.142 mmol) and under argon was added a solution of 3-chloropivaloyl chloride (0.019 ml, 0.142 mmol) in dichloromethane and stirred at room temperature over night. Added 0.5M hydrochloric acid and extracted with dichloromethane, co extracted aqueous layer with dichloromethane and the combined organic layers were washed with sodium bicarbonate and brine, dried over sodium bicarbonate, filtered and evaporated to obtain the desired N-(1-benzyl-6-(2-(1-methyl-1H-imidazole-4-sulfonamido)ethoxy)-2,3-dihydro-1H-inden-2-yl)-3-chloro-2,2-dimethylpropanamide as yellow oil. m=51 mg (quant.) that was used without further purification for the next steps.
