HCID 8028Tetrahydrofuran溶媒

実験手順

A solution of the crude sulfonyl chloride from Example 13 in 150 ml of tetrahydrofuran was cooled to 0° and treated with 7.3 ml of concentrated aqueous ammonium hydroxide. The resulting suspension was allowed to warm to room temperature. Removal of the solvent in vacuo gave an oily residue which was triturated with 300 ml water. The precipitate was collected by filtration, washed with n-butyl chloride and dried to yield 9.3 g of 2-[(N,N-dimethylamino)sulfonyl]-6-(methoxycarbonyl)phenylmethanesulfonamide as a light yellow solid, m.p. 133°-142°; IR(nujol): 3400, 3310, 1720 cm-1 ; NMR (CDCl3 /DMSO-d6): δ 2.6 (6H, s, SO2N(CH3)2), 3.8 (3H, s, CO2CH3), 5.35 (2H, s, --CH2 --), 5.3-5.9 (2H, br s, NH2), 7.4-8.3 (3H, m).
