Procedure

N-[4-[(3-Bromophenyl)amino]-3-cyano-6-quinolinyl]-4-t-butyldimethylsiloxy-2-butynamide (60mg, 0.122 mmol) was dissolved in a solution of acetic acid, tetrahydrofuran and water (3:1:1) and stirred overnight at room temperature. The solution was diluted with ethyl acetate and washed with saturated sodium bicarbonate and brine. The ethyl acetate was concentrated to give 42.2 mg (90%) of yellow solid;: mass spectrum (electrospray, m/e,): 421.0311 (M+).

Workup

  1. washwashed with saturated sodium bicarbonate and brine
  2. concentrationThe ethyl acetate was concentrated
