PHP-TREN in water is not soluble in DCM, and Cho-Chl in DCM is not miscible with H2O.

Mix occasionally, conjugate o/n at RT, DCM phase is gone after o/n conjugation

ppt with ethyl eter, + H2O to redissolve the pellet

H4 , H5, H6 (from B1) is quite soluble in isopropanol after conjugation, so need to add 1.5 ml ethyl ether to ppt conjugate
