Procedure

To a suspension of 1-(tert-butyldiphenylsilyloxymethyl)-2,6-dichloro-3-[N-methyl-N-[4-(methylcarbamoyl)-cinnamoylglycyl]amino]benzene (17.6 g) in tetrahydrofuran (138 ml) was added 1M tetrabutylammonium fluoride in tetrahydrofuran (38.4 ml) at ambient temperature. The reaction mixture was stirred for 1 hour. The mixture was concentrated and diluted with dichloromethane. The organic layer was washed with 1H hydrochloric acid, saturated sodium bicarbonate solution and water, dried over magnesium sulfate and evaporated in vacuo to give 2,6-dichloro-1-hydroxymethyl-3-[N-methyl-N-[4-(methylcarbamoyl)cinnamoylglycyl]amino]-benzene (8.14 g).
