A solution of 0.33 ml (0.975 g, 4.2 mmol) chloroacetyl chloride in 10 ml THF was cooled to 0° C. To this was added a solution of 0.8 g (3.98 mmol) 2-amino-1,1-diphenylpropanol and 0.6 ml (0.436 g, 4.31 mmol) triethylamine in 10 ml THF. The resulting solution was stirred at 0° C. for 2 hours before it was filtered and the residue washed with THF. The combined filtrate was concentration and the residue crystallized from ethyl acetate-hexane to afford 0.986 g (78%) of 2-(2-chloroacetylamino)-1,1-diphenylethanol, m.p. 178°-180° C.
