Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a 100 mL of two neck RB flask was charged with 2-[4-(hydroxy methyl)phenoxy]-1-phenylethanone (2.5 g, 10.3 mmol) and methyl 3-cyano-3-(4-hydroxyphenyl)propanoate (2.5 g, 12.4 mmol) in 50 mL of toluene. To this added tributylphosphine (3.33 g, 16.5 mmol) at 0° C. and added 1,1′-(Azodicarbonyl)dipiperidine (4.165 g, 16.5 mmol) portion wise over a period of 15 min at 0° C. After 12 h of stirring at RT, the mixture was diluted with n-hexane and stirred for 10 min. Solid formed was filtered off and the filtrate was concentrated to afford crude product which on trituration with ethyl acetate and pet ether gave pure product. (2.5 g yield: 56.1%); 1H NMR (300 MHz, DMSO-d6): δ 8.01-8.03 (d, 2H), 7.67-7.72 (t, 1H), 7.55-7.60 (t, 2H), 7.34-7.37 (d, 4H), 6.96-7.02 (t, 4H), 5.59 (s, 2H), 5.01 (s, 2H), 4.37-4.46 (m, 1H), 3.61 (s, 3H), 3.07-3.16 (m, 1H), 2.90-2.97 (m, 1H). stirred for 10 min Solid formed was filtered off the filtrate was concentrated to afford crude product which on trituration with ethyl acetate and pet ether gave pure product
