Mu 250ml matatu ane mitsipa flask ine stirrer uye thermometer, nitrocaine solution ine pH ye 4.0-4.2 inowedzerwa.Pasi pekuzadza kwakazara, yakagadziriswa simbi poda inowedzerwa pa25 ℃ kakawanda.Mushure mekuwedzera, tembiricha yekuita inokwira yega uye inochengetedza 40-45 ℃.The reaction time was 2 hours.Mushure mekusefa, masara esefa anogezwa kaviri nemvura shoma, mhinduro yekugeza inosanganiswa nefiltrate, acidified kusvika pH 5 ine dilute hydrochloric acid (10%), uye saturated sodium sulfide solution inowedzerwa pH 7.8- 8.0 kupinza munyu wesimbi mune mhinduro mhinduro.Iyo filtrate inoiswa acidified kusvika ph6 ine diki diki ye dilute hydrochloric acid, uye yobva yapiswa pa50-60 ℃ kwemaminetsi gumi nekashoma kabhoni.Iyo sefa yakasara inoshambidzwa kamwe chete nemvura shoma, mhinduro yekugeza inosanganiswa nefiltrate, yakanyoroveswa kusvika pazasi 10 ℃, uye alkalized ne20% NaOH kusvikira procaine yaparadzaniswa zvachose (pH 9.5-10.5).Sefa, geza kaviri, dzvanya uye dhonza kuti ugadzire munyu (procaine hcl)
