YieldReaction ConditionsOperation in experiment
48% With hydrogenchloride; In water; for 6.0h;Reflux; To the solution of 233 47 (16.50g, 0.3mol) in 94 HCl (150mL), 40percent 188 formaldehyde solution (70mL, 1mol) was added. The reaction mixture was stirred at refluxing for 6h and TLC analysis indicated that the reaction was completed. The mixture was cooled to room temperature and filtered to give white solid 235 48 in 48percent yield. HRMS (ESI): m/z, calculated for C10H10FNO2 196.0702 (M+H)+, found 196.0783.
With hydrogenchloride; In water; at 90℃; for 3.5h; 2 g of m-fluoro-DL-phenylalanine are suspended in 20 ml of conc. hydrochloric acid and 8 ML of aqu. 37percent formaldehyde solution and stirred during 3.5 h at 90° during which a partial solution takes place. Stirring is continued overnight at room temperature and the precipitate filtered off and washed with cold water. Filtrate, combined with the wash solutions are evaporated to dryness, the residue suspended in 50 ml of MEOH saturated with HCI and stirred overnight, during which a clear solution is formed. The solvent is evaporated, the residue dissolved in CH2CI2/MeOH (9: 1) and extracted with 2N NA2CO3 solution and brine. The organic phases are dried over NA2SO4, evaporated and chromatographed on silica gel using MeOtBu. The title compound is obtained as an oil, MS (ES+) : 210 (MH) +.
